Introduction

I have always been a big fan of giant robots since childhood and when I first got into D&D, I immediately wanted to play in a campaign world with gundams as a core mechanic. I tried several approaches, from making an entire custom rulebook, to some light reflavoring of existing material, to even buying other game systems. Unfortunately, those efforts didn't pan out. A custom rulebook requires a lot of game design expertise I didn't have, light reflavoring had many holes in the logic, and other game systems just didn't scratch that mechanical itch for me. This document is a culmination of running 5th Edition games since 2015, getting a good grasp of its many nuances, and finding a good middle ground between making something from scratch and using what's already available.

The world of Gundam is a high-technology world with very minimal supernatural elements. This setting involves battles between giant humanoid mobile weapons called mobile suits, with sometimes even bigger vehicles called mobile weapons. The custom mechanics and setting guidelines in this document are intended for most high-tech settings that include mobile suits.

This document is meant to help players and dungeon masters adapt 5th Edition's magic-heavy system and keep the rules in line with the internal logic of a high-tech setting that features mobile suits or other similar giant robots. There are new mechanics introduced, such as new conditions and new combat mechanics for warships, if only to ensure that the setting plays according to the world's logic.

It is assumed that you have a good grasp of the rules of 5th Edition D&D, as this document references the Player's Handbook several times.

Creature Types

Collectively called mobile weapons, the many kinds of giant mecha are given classifications to provide an equivalent type to the ones provided in the Monster Manual. The human pilots, on the other hand, retain their creature identification and classification as humanoid.

Size

A mobile weapon's size relative to other mobile weapon uses similar terms to that of a creature's, but indicates different spaces due to the differences in scale.

For the purposes of this guide, a creature refers to any creature relative to a humanoid's size (assuming a humanoid is Medium with a height of 4 to 8 feet), while a mobile weapon refers to any giant mecha relative to a mobile suit (assuming a mobile suit is Medium with a height of 40 to 80 feet).

Classes

The character classes dictate majority of what a character can do. Given the nature of the setting, player characters are called ace pilots and it is assumed that they have a mobile suit of their own.

Skills

The following skills are appropriate to a high-technology setting, showing the PHB equivalent of each one. If a race, background, or class feature grants proficiency in any of the PHB equivalent skills, you instead gain the skill appropriate to the setting.

Astrophysics. Your Intelligence (Astrophysics) check measures your ability to recall information on outer space phenomenon.

Machinery. Your Wisdom (Machinery) check measures your ability to get a sense of the build quality and efficiency of physical machinery.

Technology. Your Intelligence (Technology) check measures your ability to recall information on devices and programs, computer languages, design paradigms, and prototypes.

Magic as Technology

In a high-tech setting, magic is virtually non-existent, with technology taking its place in the world. This section outlines how magic would be treated in a technologically advanced setting.

Spell slots: Program slots

Program slots will be treated as renewable forms of technology, such as special ammunition that needs to be crafted, self-replicating materials, or similar, expendable items used by programs to produce certain effects. This could take the form of a handheld generator with 3D-printing materials or small drones that create small objects on the fly.

Cantrips

Cantrips are programs integrated into a special piece of equipment. For example, a firebolt program might be installed on a special gun, or the guidance program can be small bone-conduction earpieces that generate a tone to increase mental acuity.

Spellcasting Focus: Device

A device is a personal handheld piece of technology that allows its user to execute programs. These interface with the program slots and material components of a program in order to produce certain technological phenomena.

Spell Components: Program Components

A program's components are the physical requirements that need to be met in order to execute it.

Verbal (V). Most programs involve voice activation in order to execute. A character who is unable to speak or is in a soundless area can't execute a program with a verbal component.

Somatic (S). Program execution requires the selection of commands and setting up the program's parameters. If a program requires a somatic component, the executor must have a free hand to perform these gestures. Similarly, a mobile weapon must use its program execution device, such as a ranged weapon with the beam property, with a free hand in order to perform a program's somatic component.

Material (M). Instead of physical objects, material components come in the form of files that are loaded into a program as part of its execution. These files contain special algorithms, targeting solutions, or chemical computations that need to be stored in external data storage devices due to their data size or processing load.

Files can sometimes be volatile in nature, usually from data corruption through counter-hacking protocols or destruction of the data storage device due to the processing load. If a program states that a material component is consumed by the program, the executor must provide this component for each execution of the program.

Material components that are not consumed and have no monetary cost are assumed to be pre-installed in the device.

An executor must have a hand free to access a program's material components—or to hold a device—but it can be the same hand that he or she uses to perform somatic components.

Preparing Spells: Installing Programs

Installing programs involve saving a character's programs on his or her personal device. Given the complex nature of the programs and the limited memory of a device, only a few programs can be installed at a time.

Schools of Magic: Programming Languages

A programming language is looking at how a program is created and executed in order to produce specific effects.

Abjuration. Programs that are protective in nature, though some have aggressive uses. They create magnetic or electrical barriers, negate harmful effects, or harm trespassers.

Conjuration. Programs that involve the transportation of objects and mobile weapons from one location to another. Some programs manufacture mechanical mobile weapons or objects to the executor's side, whereas others allow the executor to move to another location at high speed.

Divination. Programs that reveal information, whether in the form of deep database dives of forgotten data, AI-driven forecasting, tracking and location of hidden objects, disrupting holograms, or satellite linking to see across vast distances.

Enchantment. Programs that affect the minds of others such as hacking a mobile weapon or through using certain chemicals against other pilots, influencing or controlling their behavior.

Evocation. Programs that manipulate particles, special grenades, or custom ammunition to produce a desired effect. Some call up blasts of fire or lightning. Others infuse the body with special chemicals to accelerate the healing process.

Illusion. Programs that deceive the senses or minds of others through holographic technology or hacking the imaging sensors of machinery. They cause people to see things that are not there, to miss things that are there, or to hear phantom noises.

Necromancy. Programs that interface with the body's natural healing capabilities or engage a mobile weapon's self-repair systems. Such programs can grant an extra reserve of stamina, or perform an ad hoc transfusion.

Transmutation. Programs that change the properties of a mobile weapon, object, or environment. They bolster the strength of an ally or make an object move at the executor's command.

Other Wizard Schools: Programming Speciality

A programming specialty utilizes existing programming languages that serve specific roles or functions.

Bladesinging. Programs that focus on enhancing the capabilities of an executor that chooses to engage in melee combat.

Lore Mastery. Programs that alter the code of other programs, changing its internal structure to optimize its use in the moment of its execution. In a way, lore mastery is a programming language about programming languages.

Theurgy. Programs that delve into design paradigms, mixing the aspects of the micro and macro perspectives of both studies of technology.

War Technology. Programs that are best served in a combat scenario, able to utilize programs to serve combatant needs and turning other executors' technological phenomena against them.

Divine Domains: Design Paradigms

A design paradigm is a specific area of interest for technological studies. It is a way of thinking when looking at mechanical designs from mobile weapons to programs in terms of how these elements synergize with each other and how to best operate them in live conditions. Compared to a programming language that looks at the micro level of each specific program, a design paradigm is a more holistic view of technological interaction.

Arcana. The arcana paradigm focuses on the effects of technological phenomena, delving into the intricacies of technological interaction with the natural world.

Death. The paradigm of death focuses on reusing discarded technology or tech that has "died" in order to find renewed purpose after obsolescence.

Forge. The forge paradigm focuses on the creative power of technology, producing technological phenomena that augments existing items or creates a new item from other materials.

Grave. The grave paradigm focuses on pre and post-mortem designs and serves as an in-between to the death and life paradigms.

Knowledge. The paradigm of knowledge focuses on the power of data and how it can be best gathered, processed, and utilized.

Life. The paradigm of life focuses on preservation, as opposed to the post-mortem viewpoint of the death paradigm.

Light. The paradigm of light focuses on the research and application of particle radiation technology used to survive the cold darkness of outer space.

Nature. The paradigm of nature focuses on the chemical application of technology to the natural world, protecting and preparing it from harmful effects of change.

Order. The paradigm of order focuses on the harmony of societal structure, employing programs and other technologies to optimize oration effects and obedience from others.

Tempest. The tempest paradigm focuses on the research and application of the raw meteorological and geothermal power of nature.

Trickery. The paradigm of trickery focuses on technology that enhances subterfuge operations.

War. The war paradigm is optimized for combat operations, employing technology that enhances the offensive capabilities of allied combatants.

Bard Colleges: Tactical Schools

The tactical schools are areas of specialization that implement technology to assist in making sound tactical forecasts in either combat or subterfuge.

Glamour. The school of glamour focuses on misdirection through focused attention, ensuring that enemy combatants are enthralled or distracted while keeping allies inspired.

Lore. The school of lore focuses on the historical knowledge of previous excursions, pulling from a wealth of programs from different programming languages or design paradigms to ensure a successful mission.

Swords. The school of swords is focused on independent combat operations, favoring personal enhancements over team cohesion.

Valor. The school of valor is the opposite of the school of swords, providing tactical forecasts to maximize the combat prowess of a team.

Whispers. The school of whispers is much like the school of satire, but employs more lethal methods while keeping up a social facade.

Sorcerous Origins: Techno-Organism

The techno-organism is an individual with aspects of special or unique pieces of technology melded into their body either by choice or by accident, mutating them into a hybrid form of human and machine.

Divine Soul. A divine soul techno-organism is infused with particle or radiation technology. This individual exhibits light-based capabilities, exuding dimly glowing skin or radiant circuitry coursing through their body.

Draconic. A draconic techno-organism is melded with shielding technologies, such as heat-resistant metals or the like. A draconic's body has patches of metallic pieces along their skin.

Giant Soul. A giant soul techno-organism is implanted with different chemical-infused particles such as electricity or ice mixed with ultralight compression technology. Parts of their skin have an exterior reminiscent of the particles they have in their body.

Phoenix. A phoenix techno-organism is bathed in the byproducts of high frequency particles that cause intense heating in most materials.

Sea. A sea techno-organism has components that allow greater aquatic adaptation.

Shadow. A shadow techno-organism is one who has been revived by experimental nano-machines a few moments after clinical death.

Stone. A stone techno-organism has magnetic shielding components within their body.

Storm. A storm techno-organism is infused with experimental flight technologies.

Wild. A wild techno-organism is so heavily mutated by different particles and radiation frequencies that random technological effects happen within their vicinity.

Warlock Pacts: Machine Interface

The machine interface is a sentient entity of technological or supernatural origin that has decided to form a symbiotic attachment with an individual.

Archfey. An archfey interface is a rogue terraforming AI, often granting several programs that utilize chemical effects to alter the mind.

Celestial. A celestial interface is an experimental social AI that focused on dispensing justice. In order to enforce its programming, it utilizes light particle technology to burn the guilty or heal the innocent.

Fiend. A fiend interface is a virtual assistant that has been possessed by the malevolent spirit of a once great ace pilot. This rogue consciousness utilizes technology for destructive means to feed its violent impulses.

Great Old One. A great old one interface is an ancient satellite program that has been sent to the deep recesses of outer space, but has somehow returned with a heightened sense of awareness. It uses inaudible sound frequencies and magnetic fields to alter the minds of those around it.

Hexblade. A hexblade interface is a targeting AI attached to a weapon that has gained a level of awareness. It has the one-track purpose of empowering its user, or evolving itself through weapon usage.

Raven Queen. A raven queen interface is the more benevolent, or at least more just, counterpart to the fiend. A gentler spirit that has taken on the form of a scout drone, sharing its senses with its host through a psychic connection.

Undying. An undying interface is the spirit of another ace pilot that has attempted to possess its host at the time of their near-death, only to be shunted to their mental recesses upon the individual's resuscitation.

Future Releases

For future releases, whether unearthed arcana or official content, tweak its description based on the existing classes or subclasses to better fit the setting.

Spell Restrictions

The following kinds of spells do not exist in a high-tech setting by virtue of them being tonally inconsistent or technologically impossible.

• Spells that teleport vast distances, such as the circle of teleportation or teleport spells. Shorter distances such as misty step or thunder step, however, are generally allowed.
• Spells that transport creatures to a different plane of existence such as the plane shift spell.
• Spells that banish creatures to another plane of existence such as the banishment spell.
• Spells that conjure pocket dimensions such as mordenkainen's magnificent mansion or the demi-plane spells.
• Spells that create entire locations or structures such as the temple of the gods or mighty fortress spells.
• Spells that possess another creature such as the magic jar spell.
• Spells that tamper with a creature's soul such as the soul cage spell.
• Spells that raise the dead after a lengthy period of time such as the raise dead spell.
• Spells that drastically alter the body such as the polymorph spell or the enlarge/reduce spell, however the latter can be reflavored as holographic imaging coupled with strength-boosting chemicals.
• Spells that alter reality such as the wish or time stop spells.
• Spells that create undead such as the animate undead spell cannot be used by pilots, however, it can be reflavored as a mobile weapon ability to hack into a downed mobile weapon.

While these are general guidelines, it shouldn't be a hard stop from using such spells. Leeway should be given, provided a satisfactory justification.

Programs and Spells

In general, pilots or mobile weapons execute programs. Special cases, however, such as the newtype race, can cast actual spells. In situations where both are in play, the rule of thumb is that programs cannot affect spells or vice versa. For example, a dispel magic program can only dispel other programs and not spells. Likewise, a dispel magic spell can only dispel spells and not programs.

Damage Types

The damage types outlined in page 196 of the Player's Handbook are retained as is, with the exception of force, radiant, and necrotic damage, which are all variations of particle energy.

Currency

Trade is still facilitated by monetary means, with a universally accepted currency called credits (cr).

Mobile Weapons

Mobile weapon is the collective term used for giant vehicular weapons such as a mobile suit or mobile weapon. The following rules are for using a mobile weapon.

Communication

A mobile weapon comes equipped with standard communication devices. You can speak with another mobile weapon that has a communication device or if it is inside another mobile weapon, warship, or similar vehicle within 1000 feet of you.

When you do so, you can choose whether to share video feed of your mobile weapon's cockpit. You can also choose to have a private communique with another mobile weapon, provided you know its frequency. An open channel broadcasts audio or video to all communication devices within range.

Targeting

Mobile weapons can target each other normally. A creature cannot be targeted while inside a mobile weapon and its cockpit doors are closed. Conversely, a mobile weapon is considered a gargantuan construct for creatures outside of a mobile weapon.

When targeting a creature that is Huge or smaller with an attack or single-target effect, you instead target a 50-foot square centered around your chosen target. This attack has disadvantage. On a hit, the creature takes damage as normal (see damage section below), while on a miss, it takes half as much damage. On a hit or miss, each creature within 50 feet of the target takes half as much damage as the target creature.

Damage

Mobile suits and mobile armors deal damage normally against each other.

When a Huge or smaller creature deals damage to a mobile weapon, the damage is divided by 10 (minimum of 0). Conversely, when a mobile weapon deals damage to a Huge or smaller creature, the damage is multiplied by 10.

New Conditions

The following conditions apply to mobile weapons.

New Condition: Inactive

The mobile weapon is powered down. It is incapacitated, attacks against it have advantage, and it automatically fails Strength and Dexterity saving throws. Any attack that hits the mobile weapon is a critical hit if the attacker is within 50 feet of it.

New Condition: Downed

The mobile weapon has taken enough damage to be reduced to 0 hit points. It drops whatever it's holding and falls prone, and becomes inactive. A downed mobile weapon explodes when it fails three death saving throws.

Features and Abilities

You can use any of your class features with any mobile weapon you pilot, provided that you are familiar with the mobile weapon. However, if you pilot a mobile weapon that you are not familiar with (such as hijacking it from a hangar), you must configure and customize the mobile weapon's systems by spending a number of hours up to your level. This activity can be performed in one hour sessions and you gain access to any class feature or ability available at a level equal to the total number of hours spent, in the order that they appear as you level up.

For example, if you're a 9th-level artificer, and you've spent a total of 3 hours configuring an unfamiliar mobile weapon, you pilot it as if you were a 3rd-level artificer (including program slots and the maximum program level you can execute), but you retain your ability scores, hit points, proficiencies, and proficiency bonuses.

If you pilot a mobile weapon you are completely unfamiliar with, you can only use its traits, actions and equipment indicated in its statblock, but uses your hit ability scores, hit points, proficiencies, and proficiency bonuses.

Your racial abilities are unique to you, and you can use those abilities regardless of your familiarity with the mobile weapon. Conversely, a mobile weapon's special traits, prototypes, and other equipment are unique to it, and cannot be used if the mobile weapon you're piloting does not have it.

Equipment

Equipment in a high-tech setting is vastly different from standard medieval fantasy.

The following section shows the different weapons and their properties, along with the equivalent proficiency to align with the PHB class proficiencies.

Shields

While you have a shield donned, you can use your reaction to halve any bludgeoning, piercing, or slashing damage you take from weapon attacks. You can do so a number of times equal to the AC bonus granted by the shield, and you regain the ability to do so after finishing a short or long rest, provided you spend one hour and 1 ton of scrap during that time.

Alternatively, you can do so one more time after expending all uses, after which the shield no longer grants any bonus to AC due to it being damaged. The shield can be repaired over the course of a long rest by expending tons of scrap equal to the AC bonus it grants.

If you are under the effect of a program that grants an AC bonus or change your AC, such as the mage armor program, shield program, or the shield of faith program, you can use your reaction to halve any bludgeoning, piercing, or slashing damage you take from weapon attacks once, and you regain the ability to do so at the start of your next turn, provided you are still under the effects of the program.

Weapons

Your class determines which of the new weapons you are proficient in.

There are four categories of weapons that appear in the PHB: simple melee weapons, simple ranged weapons, martial melee weapons, and martial ranged weapons.

If you are proficient in at least one weapon in a category, you become proficient in any of the weapons from the New Weapons table under the same category.

Beam Weapon Properties

Weapons that fire condensed beams of particle energy are generally called beam weapons. The following properties are exclusive to beam weaponry.

Beam. A weapon with the beam property draws power from the mobile weapon that attacked with it, expending a number of EP equal to the number indicated by the weapon. If the weapon is a ranged weapon, the EP is expended for each attack, while a melee weapon expends EP only for the first time it is used in a turn. Because weapons with the energy property don't use ammunition, the range of the weapon is instead indicated after the EP requirement.

Objects and Structures. A beam weapon concentrates damage on singular points via condensed beams of particle energy. A weapon with this property deals double damage to objects and structures.

Beam Weapon Effects. When a mobile weapon is hit with an attack from a weapon with the beam property for the first time in a turn and reduces its hit points by any amount, add the damage dice together and refer to the beam effect table (ranged or melee depending on your weapon) to determine any additional effects. The result is halved if the target is resistant to the damage.

Alternatively, the attacker can choose any other effect that requires a lower result than what was rolled.

For example, if you hit a target with a beam rifle and roll a 2 and a 3 on the damage dice, add them together to get a 5. Then look at the ranged beam effect table, with 5 being a direct hit. The 2 (the lower of the two rolls) is changed to 4, and is then added to the initial 3. You deal 7 + your ability score modifier in radiant damage against the target.

Programs as Beam Weapons

You can replicate the effect of a beam weapon when you execute a program that requires an attack roll and deals damage. As part of executing the program, you can expend a number of EP equal to twice the level of the program slot expended. If the program is a cantrip, refer to the cantrips EP cost table to determine the EP cost.

Doing so grants that program with the beam property, as if attacking with a beam weapon, although its damage type does not change. When referring to the beam effect table, the number is halved.

For example, if you hit a target with the fire bolt cantrip and you roll a 5 and a 6 on the 2d10 damage dice, add them together to get an 11 and halve the result, getting a 5. Then look at the ranged beam effect table, with 5 being a direct hit, allowing you to change the 5 (the lower of the two rolls) into a 10. Add that to the initial 6, and you deal a total of 16 fire damage against the target.

Weapon Variants for Mobile Weapons

Beam and heat variants of all melee weapons from the PHB can be used and purchased. Each of those variants have either the heat or beam property, as well as the mobile weapon property. Heat or beam variants of these weapons have an additional 10 gold prior to converting to credits, while the weight is in tons instead of pounds.

For ranged weapons, beam and kinetic variants are available, gaining the beam or kinetic property, as well as the mobile weapon property. For cost and weight, it uses similar cr cost conversion and weight usage as the melee weapon variants. Refer to the melee beam weapon EP table for EP cost.

Refer to the ranged weapon variants table to see which ranged weapons can be used for mobile weapons, along with EP cost for beam variants and kinetic type for kinetic variants. The blowgun and sling are not available.

Ammunition

The ammunition tables below shows the needed ammunition for their associated weapons.

Adventuring Gear

This section describes items that have special rules or require further explanation. The items in the Adventuring Gear table is in addition to the existing adventuring gear in the PHB.

Tools

Only one new tool is available for the new setting, with the rest of the other tools, artisan's tools, gaming sets, and musical instruments from the PHB available for use.

Warships

Warships are the cornerstones of prolonged battles.

Warship Defense Zone

A warship has automatic weapon systems called the defense zone. This serves as a screen of ordinance automatically fired around the ship in order to discourage smaller attackers.

Repairing a Warship

Ships do not regain hit points during short or long rests. Instead, its mechanics must take a number of hours during the day to perform repairs. These repairs roll the ship's hit die, but it does not expend hit dice. Instead, tons of scrap is expended. The ship travels at slow speed during this time.

Crew

The crew of a warship commands the entire vessel and are the ones who are capable of controlling the ship's many different systems. Some ships may have access to special actions for specific crew.

Crew Actions. On the ship's turn, they can also use an action to use a warship feature available to their role.

Crew Race and Class Features. Crewmen can use any class features, racial traits, and program execution, provided their role allows them to do so.

Crew Responsibilities

The following table summarizes the responsibilities of the crew aboard a ship.

Saving Throws. Refers to which saving throw the crew member can make if the ship is forced to make a saving throw. For any Intelligence, Wisdom, or Charisma checks, the crew member's ability score is used. Otherwise, the ship's ability score is used.

Skills. Refers to which skills the crew member can make if the ship needs to make an ability check. For any Intelligence, Wisdom, or Charisma checks, the crew member's ability score is used. Otherwise, the ship's ability score is used.

Responsibilities. Refers to the general area of responsibility the crew member handles.

Applicable Features. Refers to a sample list of features or abilities the crew member can use while operating the ship. Note that the indicated applicable features only serve as an example and is in no way an exhaustive list.

Captain

The captain is responsible for tactical commands and ensuring the safety of the crew. The captain can do the following actions:

Command. You direct one of the crew on to take one action that they can do. The crewman immediately uses its reaction to do so.

Execute a Program. You can execute a program using your own program slots.

Tactical Forecast. You can use the Help action on a number of mobile weapons up to your Intelligence modifier (minimum of 1) that you can see within 300 feet of the bridge.

Gunnery Chief

The gunnery chief is responsible for managing the ship's weapon systems and management of EP. If you are proficient in at least one martial weapon, you are proficient in all martial warship armaments. Otherwise, you are only proficient in simple warship armaments. The gunnery chief can do the following actions:

Weapon Attack. You can make an attack using any of the ship's weapons.

Execute a Program. You can execute a program using your own program slots and channel it through the weapon systems. The program must deal damage or cause a harmful effect.

Helmsman

The helmsman steers the ship and manages its engines. Some actions require your target to make a saving throw to resist its effects. The saving throw DC is calculated as follows:

Helmsman save DC = 8 + your proficiency modifier + your Strength or Dexterity modifier (your choice)

The helmsman can do the following actions:

Execute a Program. You can execute a program using your own program slots. The program must have an effect that alters or restores the ship's movement speed or affects Strength or Dexterity checks and saving throws.

Move. You can move the ship up to its movement speed.

Ramming Speed. Move forward up to your movement speed in a straight line. Whenever you occupy the space of another mobile weapon that is Large or smaller, it must make a Dexterity saving throw, taking 1d12 bludgeoning damage for every 50 feet of distance traveled on a failed save, or half as much on a successful save. On a success or fail, the mobile weapon is pushed to the nearest unoccupied space away from your path. If you occupy the space of another ship that is Huge or larger, your speed is reduced to 0 until the end of the current turn.

Whenever you deal damage with this action, your ship's hull takes damage equal to the same damage dice, but at the maximum value. This damage is doubled if you deal damage to another ship that is at least one size smaller than yours.

Evasive Maneuvers. You can take the Dodge acton and extend its effects to each part, weapon, and mobile weapon on the ship. Due to the quick and sudden movements, all attacks of the warship or attacks made while on the warship have disadvantage until the start of the ship's next turn. You can also move up to half your movement speed as part of the same action.

Communications

The communications officer is responsible for relaying orders and monitoring the ship's status.

Execute a Program. You can execute a program using your own program slots. The program must produce an effect that facilitates communication, such as the message program, or improves another mobile weapon's abilities.

Establish Communications. You can establish direct communications between any number of willing mobile weapon or warships within 1000 feet of the warship regardless of any area of silence or some other communications obstructions.

Reposition. Choose a number of willing mobile weapon up to your Charisma modifier that you can see within 600 feet of the warship. Each chosen mobile weapon can use its reaction and use half of its movement speed to move to an unoccupied space of your choice that you can see within 600 feet of the warship.

Signal Retreat. Recall any mobile suit or mobile armor that you can see within 900 feet of the ship. Each chosen target can use its reaction to move towards your ship without triggering opportunity attacks. You can use this feature once, and must finish a short or long rest in order to do so again.

Mechanic

The ship's mechanic is responsible for ensuring the integrity of the warship and any mobile weapon under its care. This role serves as the chief mechanic.

Execute a Program. You can execute a program using your own program slots. The program must produce an effect that restores hit points, grants temporary hit points, affects Constitution saving throws, or affects AC.

Onsite Repairs. You can repair damaged parts of the ship or damaged mobile weapon docked in the ship's hangar. You have a pool of d12s that you spend to facilitate this repair. The number of dice in the pool equals 1 + your Wisdom (Machinery) bonus. You regain expended dice by expending 1 ton of scrap for each die at the end of a long rest.

Choose one of the docked mobile weapons in the ship's hangar, one of the ship's parts other than the hull that has at least 1 hit point, or one of the ship's weapons (even with 0 hit points) spending repair dice from your pool. The maximum number of dice you can spend at once equals your Wisdom modifier. Roll the dice you spend, add them together, and restore a number of hit points equal to the total. If there are other mechanics on the ship whose Wisdom (Machinery) bonus is equal to or greater than yours, you add their Wisdom modifier to the roll.

Warships in Combat

The following rules are for warships that enter combat.
