Arcana Revised: The Artificer

<div class='pageNumber'>1</div>
<div class='footnote'>ARTIFICER</div>

# Unearthed	Arcana:	Artificer *(Revised)*

A gnome sits hunched over a workbench, carefully using needle and thread to wave runes into a leather satchel. The bag shudders as she completes her work, and a sudden, loud pop echoes through the room as a portal to an extradimensional space springs to being in the bag’s interior. She beams with pride at her newly crafted bag of holding.

A troll growls in hunger as it looms over a dwarf, who slides a long, metal tube from a holster at his belt. With a thunderous roar, a gout of flame erupts from the tube, and the troll’s growls turn into shrieks of panic as it turns to flee.

An elf scrambles up the castle’s wall, Baron von Hendriks’ men
 close behind her. As she clambers over the battlements, she reaches into her satchel, pulls out three vials, mixes their contents into a small leather bag, and flings it at her pursuers. The bag bursts at their feet, trapping them in a thick, black glue as she makes her escape.

Makers of magic-infused objects, artificers are defined by their inventive nature. Like wizards, they see magic as a complex system waiting to be decoded and controlled through a combination of thorough study and investigation. Artificers, though, focus on creating marvelous new magical objects. Spells are often too ephemeral and temporary for their tastes. Instead, they seek to craft durable, useful items.

### Cunning Inventors
Every artificer is defined by a specific craft. Artificers see mastering the basic methods of a craft as the first step to true progress, the invention of new methods and approaches. Some artificers are gunsmiths, students of invention and warfare who craft deadly firearms that they can augment with magic. Other artificers are alchemists. Using their knowledge of magic and various exotic ingredients, they create potions and draughts to aid them on their adventures. Others still are mechanists crafting clockwork servants who carryout their needs. Alchemy, mechanics, and gunsmithing are the two most common areas of study for artificers, but others do exist.

All artificers are united by their curiosity and inventive nature. To an artificer, magic is an evolving art with a leading edge of discovery and mastery that pushes further ahead with each passing year. Artificers value novelty and discovery. This penchant pushes them to seek a life of adventure. A hidden ruin might hold a forgotten magic item or a beautifully crafted mirror perfect for magical enhancement. Artificers win respect and renown among their kind by uncovering new lore or inventing new methods of creation.

\columnbreak

### Intense Rivalries
The artificers’ drive to invent and expand their knowledge creates an intense drive to uncover new magic discoveries. An artificer who hears news of a newly discovered magic item must act fast to get it before any rivals do. Good-aligned artificers recover items on adventures or offer gold or wondrous items to those who possess items they are keen to own. Evil ones have no problem committing crimes to claim what they want.

Almost every artificer has at least one rival, someone whom they seek to outdo at every turn. By the same token, artificers with similar philosophies and theories band together into loose guilds. They share their discoveries and work together to verify their theories and keep ahead of their rivals.

### Creating an Artificer
When creating an artificer character, think about your character’s background and drive for adventure. Does the character have a rival? What is the character’s relationship with the artisan or artificer who taught the basics of the craft? Talk to your DM about the role played by artificers in the campaign, and what sort of organizations and NPCs you might have ties to.

#### Quick Build
You can make an artificer quickly by following these suggestions. First, put your highest ability score in Intelligence, followed by Constitution or Dexterity. Second, choose the guild artisan background.

As an artificer, you gain the following class features.
#### Hit Points
___
- **Hit Dice:** 1d8 per artificer level
- **Hit Points at 1st Level:** 8 + your Constitution 
modifier
- **Hit Points at Higher Levels:** 1d8 (or 5) + your Constitution modifier per artificer level after 1st

\columnbreak

#### Proficiencies
___
- **Armor:** Light and medium armor
- **Weapons:** Simple weapons, hand crossbow, heavy crossbow
- **Tools:** Thieves’ tools, two other tools of your 
choice

### Magic Item Analysis
Starting at 1st level, your understanding of magic items allows you to analyze and understand their secrets. You know the artificer spells detect magic and identify, and you can cast them as rituals. You don’t need to provide a material component when casting identify with this class feature.

### Tool Expertise
Starting at 2nd level, your proficiency bonus is doubled for any ability check you make that uses any of the tool proficiencies you gain from this class.

### Wondrous Invention
At 2nd level, you gain the use of a magic item that you have crafted. Choose the item from the list of 2nd-level items below.

Crafting an item is a difficult task. When you gain a magic item from this feature, it reflects long hours of study, tinkering, and experimentation using whatever materials and means available to you that allowed you to finally complete the item. You are assumed to work on this item in your leisure time and to finish it when you level up.

You complete another item of your choice when you reach certain levels in this class: 5th, 10th, 15th, and 20th level. The item you choose must be on the list for your current artificer level or a lower level.

These magic items are detailed in the Dungeon Master’s Guide.
___
- **2nd Level:** *bag of holding, cap of water breathing, driftglobe, goggles of night, sending stones*
- **5th Level:** *alchemy jug, helm of comprehending languages, lantern of revealing, ring of swimming, robe of useful items, rope of climbing, wand of magic detection, wand of secrets*
- **10th Level:** *bag of beans, chime of opening, decanter of endless water, eyes of minute seeing, folding boat, Heward’s handy haversack*
- **15th Level:** *boots of striding and springing, bracers of archery, brooch of shielding, broom of flying, hat of disguise, slippers of spider climbing*
- **20th Level:** *eyes of the eagle, gem of brightness, gloves of missile snaring, gloves of swimming and climbing, ring of jumping, ring of mind shielding, wings of flying*

### Spellcasting
As part of your study of magic, you gain the ability to cast spells at 3rd level. The spells you learn are limited in scope, primarily concerned with modifying creatures and objects or creating items.

#### Spell Slots
The Artificer table shows how many spell slots you have to cast your spells of 1st level and higher. To cast one of these spells, you must expend a slot of the spell’s level or higher. You regain all expended spell slots when you finish a long rest.

#### Spells Known of 1st Level and Higher
You know three 1st-level spells of your choice from the artificer spell list (which appears at the end of this document).

The Spells Known column of the Artificer table shows when you learn more artificer spells of your choice from this feature. Each of these spells must be of a level for which you have spell slots on the Artificer table.

Additionally, when you gain a level in this class, you can choose one of the artificer spells you know from this feature and replace it with another spell from the artificer spell list. The new spell must also be of a level for which you have spell slots on the Artificer table.

#### Spellcasting Ability
Intelligence is your spellcasting ability for your artificer spells; your understanding of the theory behind magic allows you to wield these spells with superior skill. You use your Intelligence whenever an artificer spell refers to your spellcasting ability. In addition, you use your Intelligence modifier when setting the saving throw DC for an artificer spell you cast and when making an attack roll with one.
___

**Spell save DC** = 8 + your proficiency bonus + your Intelligence modifier <br>
 **Spell attack modifier** = your proficiency bonus + your Intelligence modifier

</center>

#### Spellcasting Focus
You can use an arcane focus as a spellcasting focus for your artificer spells. See chapter 5, “Equipment,” in the Player’s Handbook for various arcane focus options.

### Improved Magical Crafting
At 3rd level, your experience in creating your own wondrous invention makes you more adept at crafting a magic item than a normal spellcaster. You gain the following benefits:
* Any costs incurred in order to craft a magical item are reduced by half.
* You are able to make progress towards the completion of a magical item in half the normal time.
* Whenever you cast the *identify* spell on a magical item, you gain an understanding of the process and materials required for its creation.

### Infuse Magic
Starting at 4th level, you gain the ability to channel your artificer spells into objects for later use. When you cast an artificer spell with a casting time of 1 action, you can increase its casting time to 1 minute. If you do so and hold a nonmagical item throughout the casting, you expend a spell slot, but none of the spell’s effects occur. Instead, the spell transfers into that item for later use if the item doesn’t already contain a spell from this feature.

Any creature holding the item thereafter can use an action to activate the spell if the creature has an Intelligence score of at least 6. The spell is cast using your spellcasting ability, targeting the creature that activates the item. If the spell targets more than one creature, the creature that activates the item selects the additional targets. If the spell has an area of effect, it is centered on the item. If the spell’s range is self, it targets the creature that activates the item. If the spell requires concentration, the creature that activates the item maintains the concentration as if they had cast the spell.

When you infuse a spell in this way, it must be used within 8 hours. After that time, its magic fades and is wasted.

\pagebreakNum

You can have a limited number of infused spells at the same time. The number equals your Intelligence modifier.

### Ability Score Improvement
When you reach 4th, 8th, 12th, 16th, and 18th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can’t increase an ability score above 20 using this feature.

### Superior Attunement
At 5th level, your superior understanding of magic items allows you to master their use. You can now attune to up to four, rather than three, magic items at a time.

At 15th level, this limit increases to five magic items.

### Use Magic Device
By 13th level, you have learned enough about the creation of magical items that you can improvise the use of items even when they are not intended for you. You ignore all class, race, and level requirements on the use of Magic Items.

### Soul of Artifice
At 20th level, your understanding of magic items is unmatched, allowing you to mingle your soul with items linked to you. You can attune to up to six magic items at once. In addition, you gain a +1 bonus to all saving throws per magic item you are currently attuned to.

## Artificer Specialists
Artificers pursue a variety of specializations. The three most common, alchemy, mechanics, and gunsmithing, are presented here.

### Alchemist
An alchemist is an expert at combining exotic reagents to produce a variety of materials, from healing draughts that can mend a wound in moments to clinging goo that slows creatures down.

\columnbreak

#### Knowledge of Substance
When you choose this specialization at 1st level, you gain proficiency with alchemist’s supplies, and you learn the *spare the dying* cantrip.

#### Alchemist’s Satchel

At 1st level, you craft an Alchemist’s Satchel, a bag of reagents that you use to create a variety of concoctions. The bag and its contents are both magical, and this magic allows you to pull out exactly the right materials you need for your Alchemical Formula options, described below. After you use one of those options, the bag reclaims the materials.

If you lose this satchel, you can create a new one over the course of three days of work (eight hours each day) by expending 100 gp worth of leather, glass, and other raw materials.

#### Alchemical Formula
At 1st level, you learn three Alchemical Formula options: Alchemical Fire, Alchemical Acid, and one other option of your choice. You learn an additional formula of your choice at 3rd, 9th, 14th, and 17th levels.

To use any of these options, your Alchemist’s Satchel must be within reach.

If an Alchemical Formula option requires a saving throw, the DC is 8 + your proficiency bonus + your Intelligence modifier.

***Alchemical Fire.*** As an action, you can reach into your Alchemist’s Satchel, pull out a vial of volatile liquid, and hurl the vial at a creature, object, or surface within 30 feet of you (the vial and its contents disappear if you don’t hurl the vial by the end of the current turn). On impact, the vial detonates in a 5-foot radius. Any creature in that area must succeed on a Dexterity saving throw or take 1d6 fire damage.

This formula’s damage increases by 1d6 when you reach certain levels in this class: 4th level (2d6), 7th level (3d6), 10th level (4d6), 13th level (5d6), 16th level (6d6), and 19th level (7d6).

***Alchemical Acid.*** As an action, you can reach into your Alchemist’s Satchel, pull out a vial of acid, and hurl the vial at a creature or object within 30 feet of you (the vial and its contents disappear if you don’t hurl the vial by the end of the current turn). The vial shatters on impact. A creature must succeed on a Dexterity saving throw or take 1d6 acid damage. An object automatically takes that damage, and the damage is maximized.

This formula’s damage increases by 1d6 when you reach certain levels in this class: 3rd level (2d6), 5th level (3d6), 7th level (4d6), 9th level (5d6), 11th level (6d6), 13th level (7d6), 15th level (8d6), 17th level (9d6), and 19th level (10d6).

***Flash Bomb.*** As an action, you can reach into your Alchemist's Satchel and pullout a clay pot filled with explosive flash powder, and hurl it at a point on the ground within 30 feet of you (the pot and its contents disappear if you don't hurl the pot by the end of the current turn). The pot explodes on impact, producing a bright flash. Each creature within ten feet of the point of impact must succeed on a Constitution saving throw or become blinded until the end of your next turn. After using this formula, you can’t do so again for 1 minute.

\pagebreakNum

***Healing Draught.*** As an action, you can reach into your Alchemist’s Satchel and pull out a vial of healing liquid. As part of this action you can administer the vial to another creature, alternatively a creature can drink it as an action to regain 1d8 hit points. The vial then disappears. Once a creature regains hit points from this alchemical formula, the creature can’t do so again until it finishes a long rest. If not used, the vial and its contents disappear after 1 hour. While the vial exists, you can’t use this formula.

This formula’s healing increases by 1d8 when you reach certain levels in this class: 3rd level (2d8), 5th level (3d8), 7th level (4d8), 9th level (5d8), 11th level (6d8), 13th level (7d8), 15th level (8d8), 17th level (9d8), and 19th level (10d8).

***Noxious Gas.*** As an action, you can reach into your Alchemist's Satchel and pullout a glass vial greenish brown fluid, and hurl it at a point on the ground within 30 feet of you (the vial and its contents disappear if you don't hurl the vial by the end of the current turn). The vial shatters on impact, producing a cloud of poisonous fumes. Each creature within 15 feet of the point of impact must succeed on a Constitution saving throw or become poisoned for 1d4 rounds, roll a separate d4 for each creature affected. After using this formula, you can’t do so again for 1 minute.

***Smoke Stick.*** As an action, you can reach into your Alchemist’s Satchel and pull out a stick that produces a thick plume of smoke. You can hold on to the stick or throw it to a point up to 30 feet away as part of the action used to produce it. The area in a 10-foot radius around the stick is filled with thick smoke that blocks vision, including darkvision.  The stick and smoke persist for 1 minute and then disappear. After using this formula, you can’t do so again for 1 minute.

***Stunning Powder.*** As an action, you can reach into your Alchemist's Satchel and pullout a pouch of fine powder and fling it in a direction you choose (the pouch and its contents disappear if you don't hurl the pouch by the end of the current turn). The contents spill forth, producing a spray of fine powder. Each creature within a 10 foot cone in front of you must succeed on a Constitution saving throw or become stunned until the end of your next turn. After using this formula, you can’t do so again for 1 minute.

The range of this formula increases when you reach certain levels in this class: 7th level (15 feet), 13th level (20 feet), and 19th level (25 feet).

***Swift Step Draught.*** As a bonus action, you can reach into your Alchemist’s Satchel and pull out a vial filled with a bubbling, brown liquid. As an action, a creature can drink it. Doing so increases the creature’s speed by 20 feet for 1 minute, and the vial disappears. If not used, the vial and its contents disappear after 1 minute. After using this formula, you can’t do so again for 1 minute.

***Tanglefoot Bag.*** As an action, you can reach into your Alchemist’s Satchel and pull out a bag filled with writhing, sticky black tar and hurl it at a point on the ground within 30 feet of you (the bag and its contents disappear if you don’t hurl the bag by the end of the current turn). The bag bursts on impact and covers the ground in a 5-foot radius with sticky goo. That area becomes difficult terrain for 1 minute, and any creature that starts its turn on the ground in that area has its speed halved for that turn. After using this formula, you can’t do so again for 1 minute.

***Thunderstone.*** As an action, you can reach into your Alchemist’s Satchel and pull out a crystalline shard and hurl it at a creature, object, or surface within 30 feet of you (the shard disappears if you don’t hurl it by the end of the current turn). The shard shatters on impact with a blast of concussive energy. Each creature within 10 feet of the point of impact must succeed on a Constitution saving throw or be knocked prone and pushed 10 feet away from that point.

#### Improved Potion Making
At 3rd level, you are able to use your magical abilities to twist the effects of a potion. Upon the completion of a potion choose one of the following effects if applicable:
* If the potion has a duration it is doubled.
* You may add your Intelligence ability modifier to one dice roll for damage or healing caused by the use of the poition. 
* The potion can be used as a bonus action.

Once you use this feature you cannot do so again until you complete a long rest.

#### Potent Reagents
Starting at 6th level, you gain the ability to create superior concoctions using your Alchemist's Satchel. When you use an Alchemical Formula that requires a target to make a saving throw against the effect, you may impose disadvantage on a target's saving throw.

You can do this a limited number of times each long rest. The number equals your Intelligence modifier.

#### Formula Focus
At 9th level, you select one of your Alchemical Formulas which requires you to roll damage or healing. You may add your Intelligence modifier to the roll.

You choose another formula for this feature at 14th level.

#### Perfect Concoction
At 17th level, when you use an Alchemical Formula that you have selected for your Formula Focus, you may choose to deal maximum damage or provide maximum healing instead of rolling.

Once you use this feature for a formula, you must finish a short or long rest before you can use it again on the same formula.

\pagebreakNum

<div class='pageNumber'>6</div>
<div class='footnote'>ARTIFICER</div>

### Mechanist
Artificers whose expertise extends beyond enchantment, into clockwork marvels and mechanical tinkering, are known as Mechanists.

#### Mechanics Knowledge
When you choose this specialization at 1st level, you gain proficiency with tinker’s tools, and you learn the *shocking grasp* cantrip.

#### Mechanical Servant

At 1st level, you complete a mechanical servant, formed from metal and clockwork. The servant is a construct that obeys your commands without hesitation and serves you loyally. Though magic fuels its creation, the servant is not magical itself. You are assumed to have recently succeeded in this creation after working towards it for sometime.

When you build your mechanical servant, you determine its game statistics by selecting a chassis and a build, which you apply to the the  mechanical servant statistics provided at the end of the Mechanist description. Your construct's chassis determines its general appearance, but it can look however you like, as long as its form is appropriate for those statistics.

The construct has its own proficiency bonus which matches your own. It increases in level whenever you do, and gains a new hit die, just as you do. Your servant may spend hit dice to heal duuring a short rest, however you must be present and able to make repairs. Long rests for the construct follow the same rules as players.

Additionally, whenever you gain an ability score increase from this class, your servant gains an ability score increase of its own, however the construct’s Intelligence and Charisma scores cannot be increased through this feature.

The servant obeys your orders to the best of its ability. In combat, it rolls its own initiative and acts on its own. Your mechanical servant can’t attack, but it can take other actions as normal.

If the servant is killed, it can be returned to life via normal means, such as with the *revivify* spell. In addition, over the course of a long rest, you can repair a slain servant if you have access to its body. It returns to life with 1 hit point at the end of the rest.

If the servant is beyond recovery, you can reproduce the construct exactly as it was, with four days of work (eight hours each day) and 1,000 gp of raw materials.

#### Combat-Ready Construct
Starting at 3rd level you are able to create weapon components for your construct. Choose 2 simple weapons, the mechanical servant is considered proficient with the chosen weapons. The constuct gains the attack action, and follows the normal rules for wielding weapons and attacking.

These weapons may take a different form than a normal weapon. For example, curved blades may be attached to the wings of a flying construct, enabling it to deal slashing damage like a simitar. Whatever its physical description, you can use the game statistics provided for the weapon in chapter 5 of the Player's Handbook.

Additionally, the construct gains proficiency in all saving throws.

\columnbreak

#### Upgraded Construct
At 3rd level you improve your construct by upgrading or adding components. You make three upgrades of your choice to your servant from the Mechanical Servant Upgrades list, detailed at the end of the Mechanist description.

You choose an additional two upgrades each at level 6 and level 9, and one additional upgrade each at level 14 and level 17.

#### Magic Imbued Strikes
Starting at 6th level your servant’s attacks count as magical for the purposes of overcoming resistances and immunity from non-magical attacks and damage.

#### Defensive Response
At 9th level, if you are attacked and the attacker is within 5 ft of your construct, your construct can make a single melee attack against the attacker as a reaction.

### Mechanical Servant Statistics
Your mechanical servant uses these base statistics when created.

### Mechanical Servant Chassis
The basic physical form of your construct, including its size and speed. The specifics of its appearance can be tailored to your choosing.

#### Aerial Chassis

You construct a smaller, lighter chassis capable of flight. The servant gains the following additions to its statistics.
- **Size** small
- **Skills** acrobatics
- **Speed** 10 ft., fly 40 ft.
- **Hit Die** d6
- **Hit Points at 1st Level** 6 + its Constitution modifier
- **Hit Points at Each Level After 1st** 4 (or 1d6) + Constitution modifer

\pagebreakNum

<div class='pageNumber'>7</div>
<div class='footnote'>ARTIFICER</div>

#### Biped Chassis

You construct a chassis built to stand upright on two legs. The servant gains the following additions to its statistics.

- **Size** medium
- **Skills** athletics
- **Speed** 30 ft., climb 30 ft.
- **Hit Die** d8
- **Hit Points at 1st Level** 8 + its Constitution modifier
- **Hit Points at Each Level After 1st** 5 (or 1d8) + Constitution modifer

#### Quadruped Chassis

You construct a chassis designed to move quickly using 4 legs. The servant gains the following additions to its statistics.
- **Size** medium
- **Skills** athletics, acrobatics
- **Speed** 40 ft.
- **Hit Die** d8
- **Hit Points at 1st Level** 8 + its Constitution modifier
- **Hit Points at Each Level After 1st** 5 (or 1d8) + Constitution modifer

> ##### Expanding Chassis Options
>Depending on the nature of your campaign, and your interests as a the player, the DM might choose to expand the options for your mechanical servant. Any form for a servant can do, but these general guidelines should be followed.
>* The chassis size should not exceed medium
>* Skills should not be added that are available via upgrades
>* Mechanical benefits, such as a fly speed, should be offset by negatives, such as small size, or lack of features, such as a single skill proficiency.
>* Special abilities or extreme values can be used sparingly, but again should be offset. For example creating a limbless tank-like chassis with a d10 hit die, but a slow land speed.

### Mechanical Servant Builds
The manner in which you build your mechanical servant is just as important as its components and design. The build determines your construct's strengths and weakenesses.

#### Strong Build

- The servant gains a Strength score of 16.
- The servant gains either a Wisdom, Dexterity, or Constitution score of 13.
- Some Construct features require the target to make a saving throw to resist. The construct’s saving throw DC is calculated as follows:

**Construct save DC** = 8 + *proficiency bonus* + Strength modifier

</center>

\columnbreak

#### Flexible Build
- The servant gains a Dexterity score of 16.
- The servant gains either a Wisdom, Strength, or Constitution score of 13.
- Some Construct features require the target to make a saving throw to resist. The construct’s saving throw DC is calculated as follows:

**Construct save DC** = 8 + *proficiency bonus* + Dexterity modifier

</center>

#### Intircate Build
- The servant gains a Wisdom score of 16.
- The servant gains either a Strength, Dexterity, or Constitution score of 13.
- Some Construct features require the target to make a saving throw to resist. The construct’s saving throw DC is calculated as follows:

- The servant gains either a Strength, Dexterity, or Wisdom score of 13.
- Some Construct features require the target to make a saving throw to resist. The construct’s saving throw DC is calculated as follows:

**Construct save DC** = 8 + *proficiency bonus* + Constitution modifier

</center>

### Mechanical Servant Upgrades	
If a construct upgrade has prerequisites, you must meet them to perform it. You can perform the upgrade at the same time that you meet its prerequisites. You cannot select the same upgrade twice.

#### Advanced Materials
*Prerequisite: 14th level Artificer*

By utilizing rare ore in upgrading the construct’s armor, the construct gains resistance against bludgeoning, piercing, and slashing from nonmagical weapons.

#### Aquatic Adaptation
Using a special compound that you develop, you coat your construct in a friction reducing material. You attach fins, webbing, or other appropriate aquatic locomotive aids.
