Blood Magic 1.1

The following is a preview of the Blood Magic Expansion. This is unfinished content cut together from several drafts, so don't take anything too literally yet, but feel free to add any thoughts or strong feelings.

Limited Availability

Blood magic is not restricted by an special feat or requirement, but your DM may rule that there are special requirements to learn blood magic. The only inherent restriction is that to use only hit points to cast blood magic is restricted to the Hemomancer feat or the Occultist's Blood Magic rite.

Testing Notes


Disclaimer: Sensitive Content

Blood magic is an inherently somewhat dark subject matter that might not be suitable for all adventures or adventurers, even as a tool of the villains.

While this version of blood magic is intentionally fairly sanitized and does not include any graphic descriptions, leaving as much as practical to the collective imagination, this may be something you want to discuss with your table to see if it would be a valuable addition to your game before adding it.


Why Not Hit Dice?

A popular solution to Blood Magic is to make it cost hit dice, but this tends to lead to an unhealthy design pattern of making casters even more powerful in a single fight, while further reducing the benefits of short resting for them, which is the opposite of what generally makes for balanced design.

Blood magic should be, as much as possible, a powerful new option rather than a way to spend resources as fast as possible for peak optimization (something it is already prone to by its nature).


Blood Magic Balance

Blood magic is used by spellcasters because they want additional power. People don't sacrifice vitality just for fun if normal magic would do the job just as well (usually). This makes a natural challenge for game mechanics.

The position of this document is that using the vitality of your own blood is balanced by the drawbacks of doing so, with a cost to it that roughly equals the benefit. A meaningful but neutral choice. Using blood from other creatures via sacrifice is not mechanically balanced in the same way: it's balanced vs. externalities (being restricted in access, and probably sort of evil). Most villains do evil things because it gives them power, and blood magic is no exception.

Blood Magic Spells

Blood Components

Blood magic spells all have a material component that reads "a drop [or splash] of blood worth [X] hit points". If a a material component is "up to X '' number of hit points, it can be as little as 1 hit point up to the amount listed.

When you cast a blood magic spell, you take damage equal to the blood required for the spell, which you can draw as part of casting the spell (no additional action required). This blood must come from you, unless you have features or feats that allow you to use other sources of blood to power your magic.

If you cast a Blood Magic spell at a higher level, the minimum hit points increases to the level the spell is cast at.

You cannot spend more hit points than you have this way.

Blood Damage

Damage taken from casting blood magics reduces your current hit points and bypasses any temporary hit points or damage reduction you have (as you need blood to power the spell).


Concentration

While not universally true, many blood magic spells lack the Concentration requirements of normal spells. This is intentional, and part of what makes them appealing options to mages, but is also somewhat necessary as blood mages often take small amounts of damage from casting their spells, making it easy for them to lose concentration to their own spell casting otherwise.

Blood Magic Type

Spells with the (blood magic) tag are considered to be Blood Magic spells. The Blood Magic type is a subtype of Arcane, meaning all Blood Magic spells are considered to be Arcane type by default.

The piercing and necrotic damage increase by 1d6 at 5th level (2d6), 11th level (3d6), and 17th level (4d6). The blood consumed also increases when the damage increases at 5th (2), 11th (3), and 17th (4).

On failure, they are drained of their blood by the swirling storm of Striges, reducing their hit points by 4d4 + 12 damage and restoring 4 hit points to the caster. On a successful save, they half as much damage and restore 2 hit points to caster.

Feats

Hemomancer

Prerequisite: Spellcasting or Pact Magic Feature


You can sacrifice your essence to cast blood magic spells in place of expending a spell slot. To do so, sacrifice 5 hit points per level of the spell. These hit points sacrificed can count towards the hit point cost of the blood Material component of the spell.

You can cast a total number of spell levels in this manner equal to your character level, but casting a spell of 6th level or higher this way drains your vitality in a more profound way unless it has the blood magic tag, causing you to gain levels of exhaustion equal to the number of levels over 5th the spell is (1 level for a 6th level spell, 2 for a 7th level spell, etc).

You cannot cast spells this way over 5th level while you have any levels of exhaustion. You regain all levels of usage of this rite when you complete a long rest.

Occultist

Occultist Rites


Blood Rituals (Prerequisite: 5th level Occultist)

Whenever you cast a ritual spell that requires a material component, you can instead use blood, draining the living vital essence of creatures to power the magic in a unique way.

Willing living creatures within 10 feet (including you) can expend hit points as part of casting the spell, with each 10 hit points sacrificed in this manner able to replace up to 100 gp of material components (for example, to replace a diamond worth 500 gold, 50 hit points would have to be expended in this manner).

Any creature that contributes a number o hit points greater than their character level (or CR if they have no level) to this ritual gains 1 level of exhaustion.


Blood Fuel

You can sacrifice your essence to cast blood magic spells in place of expending a spell slot. To do so, sacrifice 5 hit points per level of the spell. These hit points sacrificed can count towards the hit point cost of the blood Material component of the spell.

You can cast a total number of spell levels in this manner equal to your character level, but casting a spell of 6th level or higher this way drains your vitality in a more profound way unless it has the blood magic tag, causing you to gain levels of exhaustion equal to the number of levels over 5th the spell is (1 level for a 6th level spell, 2 for a 7th level spell, etc).

You cannot cast spells this way over 5th level while you have any levels of exhaustion. You regain all levels of usage of this rite when you complete a long rest.

Blood Cultist

The dark tradition of a Blood Cultist is one that seeks power at any cost. They are those prepared to give up everything for power, dedicated themselves to mysterious rituals, forbidden techniques, and whispered taboos in order to grasp hold of ancient and terrible powers. Masters of sacrifice, blood magic, and willing to cast aside their humanity (or relevant equivalent!) they are driven beyond what most would consider rational, natural, or even possible on their eternal quest to go beyond the limiting walls of mortality to find new dark powers.

Unusual Resources

Cultists are a unique type of full caster. They sacrifice the majority of their spell slots to empower themselves, which would normally leave them with little room to cast spells, but make up for that shortcoming through being able to more freely sacrifice their own hit points through Blood Magic.


Variable Casting Stat

There's a reasonable argument for Intelligence, Wisdom, or Charisma as a casting stat for the Cultist subclass. It's perfectly fine if you allow them to use any casting stat, but it's recommended to disallow multiclassing if allowing them to select casting stats other Wisdom.

Blood Casting

Starting at 1st level, you learn the blood boltK cantrip and gain the following blood magic spells as you level, and can select additional spells from blood magic when you learn new spells.

Occultist Level Spells Learned
1st crimson poisonK, sense bloodK
3rd compelled convulsionK, morbid puppetK,
5th blood explosionK, vampiric bladeK
7th exsanguinateK, macabre marionetteK
9th explode heartK, life linkK

Dark Dedication

Starting at 1st level, your hit point maximum increases by 1 and increases by 1 again whenever you gain a level in this class and you gain the ability to sacrifice spell slots for dark boons. At the end of a long rest, select up to 2 sacrifices to make from the following list.

When you sacrifice a spell slot, that spell slot is expended and cannot be regained while the boon is active. The boon ends and regains the expanded spell slot when you complete your next long rest, unless you select the same boon again at the end of that long rest continuing its effect.

The number of sacrifices you can make to receive boons increases at 3rd level (to 3), 6th level (to 4), 9th level (to 5), 12th level (to 6), 15th level (to 7), and 18th level (to 8).

When making attacks with your demonic claw, you can use your Spellcasting modifier in place of your Strength modifier for attack and damage rolls. If you have more than one claw, you can make a single weapon attack with the second claw as a bonus action after making an attack with the first claw.

Sacrificial Casting

Starting at 3rd level, you gain the Blood Fuel, granting you the feature and the included ability to cast Blood Magic spells with your hit points.

Rite: Blood Fuel

You can sacrifice your essence to cast blood magic spells in place of expending a spell slot. To do so, sacrifice 5 hit points per level of the spell. These hit points sacrificed can count towards the hit point cost of the blood Material component of the spell.

You can cast a total number of spell levels in this manner equal to your character level, but casting a spell of 6th level or higher this way drains your vitality in a more profound way unless it has the blood magic tag, causing you to gain levels of exhaustion equal to the number of levels over 5th the spell is (1 level for a 6th level spell, 2 for a 7th level spell, etc).

You cannot cast spells this way over 5th level while you have any levels of exhaustion. You regain all levels of usage of this rite when you complete a long rest.

Sanguine Power

Beginning at 6th level, when you deal piercing or slashing damage to creature that has blood, the next time you cast a spell with the Blood Magic tag before the end of your next turn, you can reduce the amount of your own hit points you need to expend by the piercing or slashing damage you dealt to that creature with that attack (you can pick the highest damage piercing or slashing damage attack you made during that time).

Demonic Ascension

Starting at 14th level, you can fully invest into the rites of your dark faith, being granted a form of terrifying power. As a bonus action, you transform into a demonic form for 1 minute, gaining the following benefits:

  • While in this form you have resistance to non-magical bludgeoning, piercing, and slashing damage.
  • Your movement speed increases by 10 feet.
  • You optionally can become large sized for duration, increasing your weapon attack damage by 1d4.
  • Each time you kill a creature, the duration of the demonic form increases by 1 minute.

Once you assume this form, you cannot assume it again until you complete a long rest.

When you cast a spell that deals damage damage on cast and has a blood magic tag, you can add your Spellcasting modifier to the damage dealt.


Sacrificial Absolution

You can cast lesser restoration on a willing creature without expending a spell slot, however when you cast it in this way you suffer any condition or effect that spell cleared.

When you reach 9th level, you can instead cast greater restoration this way. It does not consume a material component when you cast it this way. If you remove a cursed item's effect (ending its attunement to creature), it instead becomes attuned to you.


Unholy Gift

Once per turn, when you expend your own hit points to cast a spell using Blood Magic, you can cause one allied creature other than yourself within 30 feet to gain temporary hit points equal to the sacrificed hit points.


Wretched Resilience

You gain immunity to diseases, and advantage on saving throws against the poisoned condition.


Zealous Conviction

You gain advantage on saving throws against being charmed or frightened.


Zealous Dedication (Prerequisite: Zealous Conviction, 12th level Blood Cultist)

When you are reduced to 0 hit points, you can make a Spellcasting ability check with a DC of 5 + the damage taken. On success, you are reduced to 1 hit point instead.

On failure, you can expend a spell slot to increase the value rolled by an amount equal to the level of the spell slot, potentially during a failure into a success. Once you spend a spell slot to do so, you cannot do so against until you complete a short or long rest.

Hemorrhaging Curse

1st-level necromancy (blood magic)


  • Classes: N/A
  • Casting Time: 1 action
  • Range: 30 feet
  • Components: S, M (something from the target creature (such as blood, hair, or scales) which the spell consumes and a drop of your blood worth at least 1 hit point, which the spell consumes)
  • Duration: Concentration, up to 1 minute

You curse a target with unclosing wounds. If the target has taken piercing or slashing since the end of their last turn or takes piercing or slashing damage for the duration of the spell, its hit points are reduced by 1d8 at the end of each of its turns for the duration. This damage cannot be stopped by first aid, staunching the wound, or any non-magical means, but is ended if the creature is restored to full hit points by magical healing or the spell ends.

Rupturing Curse

3rd-level necromancy (blood magic, curse)


  • Classes: N/A
  • Casting Time: 1 action
  • Range: 60 feet
  • Components: S, M (something from the target creature (such as blood, hair, or scales) which the spell consumes and a drop of your blood worth at least 2 hit point, which the spell consumes)
  • Duration: Concentration, up to 1 minute

You invoke a curse on a creature you can see within range, rupturing their tendons. For the duration, the creatures hit points are reduced by 2d4 for each 5 feet they move. Creatures without blood are immune to this curse.

Bloodline Curse

5th-level necromancy (blood magic)


  • Classes: N/A
  • Casting Time: 1 action
  • Range: 120 feet
  • Components: V, S, M (something from the target creature (such as blood, hair, or scales) which the spell consumes and a drop of your blood worth at least 5 hit point, which the spell consumes)
  • Duration: Concentration, up to 1 hour

You invoke a curse on a creature's bloodline. Up to 5 creatures of your choice (other than the target) of the same creature type within range are bound to that creature by a magical curse. If a creature is directly related (ancestor, descendant, or sibling) to the target creature, the range at which they can be cursed with this bond increases to 1 mile.

When that creature becomes bloodied (reduced to less than half its maximum hit points) and again if that creature dies, all creatures effected by the curse must make a Charisma saving throw, taking 5d6 + twice the cursed creature's CR (or level) necrotic damage on failed save, or half as much on success. This curse has no effect on creatures without blood.

At Higher Levels. When you cast this spell with a 6th level slot or higher, the number of creatures you can target increases by 1 for each level above 5th. When using a 9th level spell slot, the range at which you can target a related creature can be unlimited, though you must be aware of the target's existence.

Self Targeted Curse

It's intentional you can use this curse on yourself or an allied creature to target creatures of your choice that are not allied creatures but at the same creature type. It's naturally less value as you generally won't get both the death effect as well.

Warden

Blood Forger

Blood Forgers are immediately different from other Wardens, drawing their power from something more visceral but no less primal than the forces of nature: the blood of creatures. Fundamentally tied to the essence of life that beats in the heart of every creature, they are tied to life itself, self-appointed guardians and gardeners of it, preserving, curating, and pruning.

The comfort with blood and death often makes creatures uncomfortable, but they can be as potent an ally as they are a dangerous enemy, capable of giving life as easily as taking it, able to keep the companions alive against all odds.

Blood Forge

Starting at 1st level, when you roll initiative or as a bonus action at any time, you can forge your blood into armaments. You can conjure up to two weapons or weapon and a shield at a time this way. Weapons and shields created this way are automatically equipped as part of the bonus action, and can be dismissed at any time (no action required). Shields act as a normal shield would, while weapons depend on the properties selected from the Blood Forged Weapon table below.

If you become bloodied (reduced to half your maximum hit points or less), your Blood Forged weapons deal 1d4 additional necrotic damage. The size of this die increases at 5th (to 1d6), 11th (to 1d8), and 17th (to 1d10) level.

Blood Forged Weapon Table
Properties Damage Dice
1d4 slashing + 1d4 necrotic
Light 1d6 slashing
Reach 1d6 slashing
Two-Handed 1d6 slashing + 1d6 necrotic

The damage die of these weapons are increased by any Warden class feature that increases the damage die of natural weapons. If the damage die of any d6 weapon is increased to a d8, it instead becomes 1d4 slashing and 1d4 necrotic damage. When the damage die of any weapon with multiple dice increases, you can select which damage die to increase.

Crimson Font

At 1st level, when you cast a blood magic spell, you can contribute hit points of blood up to your Warden Level to the spell without taking damage. Any hit points contributed beyond that reduce your hit points as normal. You are immune to any effect that drains your blood or makes you bleed.

Innate Magic

Additionally when you select this bond, you gain access to several innate magical abilities by channeling the power of your primal connection.

You gain the following spells at the listed levels, and can cast each spell once without components or spell slots. Once you cast the spell in this way, you cannot cast it again until you complete a long rest. Wisdom is your spellcasting modifier for these spells. You can cast a spell again before completing a long rest by spending 1 + the level of the spell Endurance Dice.

Blood Warden Spells
Warden Level Innate Spells (1/long rest each)
1st blood transfusionK
3rd sense bloodK
5th morbid puppetK
9th crimson tideK
13th locate creature
17th ichorous bloodK

Life Bond

Additionally at 3rd level, once per turn, when a creature within range of your Primal Interdiction takes damage, you can give one (or more if if multiple creatures take damage at the same time) resistance to the damage taken (no action required). When you do so, you take the same amount of damage (after the resistance is applied).

Restore Vitality

Starting at 7th level, your Innate Magic ability to cast blood transfusion without expending a spell slot is refreshed when you complete a short rest. When you cast blood transfusion on a target other than yourself, you can expend hit points up to your Warden level (instead of up to 5), increasing the amount it heals the target based on the spell effect.

Reaper's Harvest

Additionally at 7th level, once per turn while you are bloodied (at less than half your maximum hit points) and deal necrotic damage to an enemy, you regain hit points equal to your Constitution modifier. This cannot restore hit points beyond half of your maximum hit points.

Life Control

Starting at 14th level, you are under the effects of death ward until the effect is triggered, ending the effect as normal. You regain this effect when you complete a long rest.

Additionally, when a creature makes a death save within 60 feet of you, you can use your reaction to turn the roll into a 20, allowing them to recover with 1 hit point. Once you do so, you cannot do so again until you complete a long rest.

Blood Domain

Starting at 17th level, as a bonus action you exert influence over the blood of creatures within 20 feet for 1 minute. All allied creatures of your choice within range gain resistance to slashing and piercing damage, while all hostile creatures in range bleed profusely when taking piercing or slashing damage, taking an additional 10 damage at the start of their turn if they've taken piercing or slashing damage since the end of their last turn.

Additionally, once during the effect as an action, you can exert your full control over the field to cast to cast hold monster or hold person at the 5th level without expending a spell slot targeting a creature (or creatures if the spell targets multiple creatures) affected by the domain. When you cast it this way, if a creature passes their saving throw against the effect, they are under the effect of slow until the start of your next turn.

Creatures without blood are unaffected by the blood domain. Once you use this ability, you cannot use it again until you complete a long rest.

Spellblade

Sanguine Sword

Spellblades of the Sanguine Sword are rare and feared lot, blood seekers that fuel their bloody rampages with the blood they spill. They slash their way through hordes in a never ending flurry of blood, magic, and blade, their fallen foes feeding further violence.

Those that follow the Sanguine Sword are not inherently evil - or at least not all view themselves as such - but the slaughter fueled nature of their powers provide a dark path of temptation, the next kill always offering a temptation to drive the slaughter further. Even their staunchest ally may give them a wide berth on the battlefield, while many will dismiss them as more savage beast than hero, regardless of their goals and intentions.

Sacrificial Blade Spells

You learn the following spells at the following levels. The following are Spellblade spells for you, but do not count against your spells known. Additionally, all spells with the "Blood Magic" tag are added to the Spellblade spell list for you.

Spellblade Level Spells Learned
3rd blood slashK
5th bloody burstK
9th vampiric bladeK
13th exsanguinateK
17th explode heartK

Blood Stained Blade

Starting at 3rd level, when you select this archetype, you gain special affinity when wielding a blood-coated weapon. For 1 minute after a melee weapon deals 1 more points of damage to a living creature that has blood, you can use use your Intelligence modifier, instead of your Strength or Dexterity modifier for attack and damage rolls with that weapon. A weapon bloodied in this way is consider magical for the purposes of overcoming resistance to non-magical damage.

You can sacrifice 1 of your own hit point at any time (no action required) to bloody a blade activating this effect.

Sanguine Surge

Starting at 3rd level, you gain a new option for your Arcane Surge feature:

  • When you cast a spell with the Blood Magic tag, you can expend an Arcane Surge to gain temporary hit points equal to your spellcasting modifier + half your spellblade level (rounded down).

Catharsis of Carnage

Starting at 7th level, when you make an attack that is a critical strike or that bloodies or kills a creature that is CR 1/4 or higher, you regain one use of Arcane Surge.

If you are bloodied when you trigger this ability, you additional regain hit points equal to your proficiency spellcasting modifier.

Gore and Gibblets

Starting at 15th level, your score a critical strike on a 19 or 20 when making an attack roll.

Additionally, when your attack kills a creature, damage dealt by Splash Damage is to nearby creatures is increased to 2d8.

Red Eyed Rampage

Starting at 20th level you fall into a bloody-crazed trance of slaughter (no action required). For the duration, you gain a truesight of 120 feet against bloodied creatures and have advantage on attack rolls against them. Once per turn for the duration, when you trigger Catharsis of Carnage, can immediately take an additional action.

Warlock

The Bloodbound

The Bloodbound Patron is an ancient and powerful entity of blood. Ancient vampires or other creatures that feast on the power of blood are most often, but there is a primordial power to blood that has created many ancient entities with deep ties to the secrets of life and death that may be sought for the impressive eldritch powers. As a warlock with a Bloodbound Patron, you gain unique abilities to manipulate blood and the life force of creatures.

Blood Patron Expanded Spells

Spell Level Spells
1st inflict wounds, false life
2nd bloody burstK, compelled convulsionK
3rd crimson tideK, invest lifeK
4th blood frenzyK, vital surgeK
5th dominate person, life supportK

Life Drain

At 1st level, you gain the ability to drain the vitality of other creatures through their blood. When you hit a creature with an attack, you can use your bonus action to drain their life, dealing additional necrotic damage equal to your Charisma modifier and regaining life equal to the necrotic damage dealt.

You can use this feature a number of times equal to your proficiency bonus, regaining all uses when you complete a long rest.

Beating Hearts

Starting at 1st level, you can sense the beating heart of life in creatures around you. You can use your spellcasting modifier, instead of your Wisdom modifier, for making Perception and Insight checks against living creatures with blood, and to your passive scores to sense living creatures.

You can heighten this sense further by casting sense blood without expending a spell slot or material component, but once you do so, you cannot do so this way again until you complete a long rest.

Sanguine Empowerment

Starting at 6th level, you can sacrifice your hit points to empower your magic. When you expend a Pact Magic spell slot to cast a spell that has an effect that scales with spell level, you can expend a number of hit points equal 1 + to the level of the spell to increase the level at which you cast the spell by one level (for example, if you cast the 2nd level spell hold person using a 3rd level Pact Magic Spell slot, you could expend 3 hit points to cast it at the 4th level).

When you cast a cantrip, you can scale the cantrip to its next level of power (for example, casting it as if you were 11th level) by spending 3 hit points this way. This works even when you are 17th level, and the cantrip would generally not scale further (adding an additional die or firing an additional beam in the case of eldritch blast).

You can spend a total number of hit points this way equal to your Warlock level, after which you cannot spend more hit points to empower your spells until you complete a long rest.

Vital Reserves

Starting at 10th level, your maximum hit points are increased by your Warlock level.

The Hunger

Beginning at 14th level, you can temporarily transform into a powerful blood avatar that devours blood. As an action, you assume this form for 1 minute, gaining the following powers:

  • You have resistance to bludgeoning, piercing, and slashing damage from non-magical attacks.
  • You have advantage on attack rolls against bloodied creatures (creatures with less than half of their maximum hit points).
  • You can use Life Drain without expending uses of the feature.
  • When you use Sanguine Empowerment, you gain temporary hit points equal to the hit points expended.

This form ends early if you end your turn without dealing or receiving damage since the start of your last turn or if you become incapacitated. Once you use this feature, you cannot use it again until you complete a long rest.

Greater Blood Rituals

[Coming Soon]

Blood Magic Items

Assassin's Token

Wonderous Item, Common

A glittering garnet necklace. As an action, you can use this necklace to absorbs all shed blood within 50 feet, including that from bloodstains, cleaning blood from a surfaces, objects, or and creatures within range without a trace. This effect does not cause any damage or stop a creature from bleeding.

Blood Stone

Wonderous Item, Rare (requires attunement)

A glittering ruby gem set into a pendant that stores vital energy. Each time you cast a spell with the Blood Magic tag, the ruby gains charges equal to the number of hit points expended to cast the spell, up to a maximum of 20.

The first time you would be reduced to 0 hit points, you instead are reduced to 1 hit point, and then instantly regain a number of hit points equal to the charges stored by the ruby.

The ruby cannot regain additional charges until dawn the next day. If the ruby has any charges at dawn, it loses 5 charges.

Sacrificial Dagger

Dagger, Wondrous Item, Uncommon (requires attunement by an evil creature)

A wicked dagger eternally stained with blood. When you hit a living creature with it, that creature takes an extra 1d6 necrotic damage.

When you kill a creature (that is not an undead or construct) with this dagger you can fuel an ongoing Greater Blood Ritual with a Ritual Focus within 30 feet, granting a value equal to the creatures CR (or level) in ritual points.

Balanced by Evil

The sacrificial dagger is an obviously overpowered item. Evil villains wouldn't (generally) be evil if it didn't make them more powerful - that's why they are evil. If you play a game without alignment or concern for morality (or the players are playing villains), the item should be considered as a Very Rare rarity instead.

  • The Blood Seeker Spellblade subclass added

Bloodbound Warlock

  • Name updated from the placeholder "The Blood" to "The Blood Bound".
  • Made Sanguine Empowerment somehow more convoluted, but probably more functional in practice.

Blood Cultist

  • Cultist renamed Blood Cultist just to make it a little less odd to have a Cultist class for Occultist, as well as because it's blood magic themed.
  • Abandoned Humanity added.
  • Leeching Power added.
  • Sacrificial Absolution added.
  • Wretched Resilience added.

Blood Forger

  • Innate Spells adjusted. Cure Wounds replaced with Blood Transfusion and Hold Person replaced with Crimson Tide.
  • Restore Vitality correspondingly tweaked to work with Blood Transfusion instead of Cure Wounds. This is effectively a buff as now it restores double the sacrificed hit points, giving Blood Forgers more incentive to expend their hit points and drop into the bloodied range.

Items

  • Assassin's Token added.
  • Blood Stone added.

Spells

  • Vampiric Blade tweaked. The math is ultimately similar, but this should be easier to track, since now you don't need to do as much math and tracking, just count the number of times you hit.
  • Blood Storm added.
  • Blood Blade added.

1.1

Sanguine Sword

  • Renamed.
  • Revamped.
  • Sanguine Surge has been changed, restoring a more standard amount of hit points and making it someone flexible. This nerfs the strongest use cases, and buffs the average use case of it.
  • Catharsis of Carnage reworked by replacing the entire effect with the 15th level ability.
  • A new 15th level ability brought in, Gore and Gibblets. This doesn't really fit the mold of Spellblade 15th level abilities, but indirectly does, as it fuels more Arcane Surges, and mostly just fits the carnage theme and slaughter themes.
  • Red Eyed Rampage is unchanged, but better synergizes with Catharsis of Carnage due to the new 15th level ability (since critical strikes are twice as likely).

Spells

  • Blood Wave added.
