Spellcasting

Your blood has been infused with an ancient magic and you have learned to channel your blood's magic into wieldable arcane energy. This blood-infused arcane energy allows you to cast spells. See chapter 10 of the Player's Handbook for the general rules of spellcasting and see the appendix on the last page for the hemomancer spell list.

Spell Slots

The Hemomancer table shows how many spell slots you have to cast your spells of 1st level and higher. To cast one of these hemomancer 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 two 1st-level spells of your choice from the hemomancer spell list.

The Spells Known column of the Hemomancer table shows when you learn more hemomancer spells of your choice. Each of these spells must be of a level for which you have spell slots.

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

Spellcasting Ability

Constitution is your spellcasting ability for your hemomancer spells, since their power comes directly from their blood. You use your Constitution whenever a spell refers to your spellcasting ability. In addition, you use your Constitution modifier when setting the saving throw DC for a hemomancer spell you cast and when making an attack roll with one.

Spell save DC = 8 + your proficiency bonus + your Constitution modifier Spell attack modifier = your proficiency bonus + your Constitution modifier

Spellcastng Focus

You can use an arcane focus as a spellcasting focus for your hemomancer spells.

Blood Magic

Casting spells as a hemomancer requires you to draw on your vitality. When you cast a hemomancer spell, you take necrotic damage based on the level that the spell is cast at. See the Blood Magic Damage table for reference.

Blood Magic Damage

Spell Level	Damage
1st	1d8
2nd	2d8
3rd	3d8
4th	5d8
5th	6d8
6th	8d8
7th	10d8
8th	12d8
9th	14d8

If the damage you take from casting a spell causes you to fall unconscious, the spell is not cast but the spell slot is still expended and you still take the damage. Additionally, the necrotic damage you take from casting hemomancer spells cannot be reduced or negated by resistance or immunity.

In addition to taking damage from casting spells, the act of drawing on your vitality makes your hemomancer spells more potent. When you cast a hemomancer spell, the spell will be considered to have been cast one level higher than the level at which you chose to cast it. This consideration excludes the

damage you take from casting a spell and this level increase occurs even if you do not yet have access to spell slots for the level that the spell is increased to.

For example, if you cast Magic Missile at 2nd-level, a 2nd-level spell slot will be expended and you will take 2d8

necrotic damage before the spell is cast, but the spell will act as though it were cast at 3rd-level. This would occur even if you did not yet have access to 3rd-level spell slots.

Spells cast at 9th-level are the only exception, since they cannot be increased any further.

Extraordinary Fortitude

The ancient magic that resides in your blood strengthens your overall vitality and resilience. At 1st level, your hit point maximum increases by 2 and increases by 2 again whenever you gain a level in this class.

Additionally, you have resistance to poison damage and advantage on saving throws against being poisoned.

Plasma Shield

Beginning at 2nd level, you can expend a spell slot and use your reaction to impose a shield of blood between you and the source of damage when you are hit. When you do so, the damage you take is reduced by 1d8 per level of the spell slot you expend + your Consitution modifier + your hemomancer level.

Arcane Transfusion

By 3rd level, your arcane blood has become more adaptable. As a bonus action, you can choose to either sacrifice your hit points to recover an expended spell slot or expend a spell slot to regain hit points. The cost to recover a spell slot and the amount of hit points you gain from expending one varies depending on the level of the spell slot. See the Arcane Transfusion Costs table for reference.

Arcane Transfusion Costs

Slot Level	Recovery Cost	Hit Points Regained
1st	25 Hit Points	1d8
2nd	45 Hit Points	2d8
3rd	60 Hit Points	3d8
4th	70 Hit Points	5d8
5th	80 Hit Points	6d8

Bloodline

At 3rd level, you choose a bloodline to follow: Sangromancy or Blood Seeker, both detailed at the end of the class description. Your choice grants you features at 3rd level and again at 7th, 11th, and 15th level. One feature granted by your bloodline will also improve at 13th level and again 17th level.

Ability Score Improvement

When you reach 4th level, and again at 8th, 12th, 16th, and 19th 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.

1 action or 1 bonus action. Until the start of your next turn, every hemomancer spell you cast deals twice as much necrotic damage to you when you cast it. You can use this feature twice between long rests, but only once per turn.

Blood Seeker

Those who hunt for the blood of others choose the Blood Seeker bloodline.

Bonus Proficiency

When you choose this bloodline at 3rd level, you gain proficiency with martial weapons, medium armor, and shields.

Plasma Weapons

Starting when you choose this bloodline at 3rd level, you gain the ability to form weapons and shields out of your blood. You can use a bonus action to create a weapon, a shield, two weapons, or a weapon and a shield. The weapons can be melee weapons or ranged weapons if they have the thrown property. The weapons can be the same or different, but you can only maintain two plasma armaments at a time. For each armament you create, you take 2d8 necrotic damage. This damage cannot be reduced or negated by resistance or immunity.

The created armaments have all of their normal characteristics and they gain the following features.

• These armaments have a +1 bonus and you use your Constitution modifier for any attack and damage rolls you make with them.
• Each time you attempt to make an attack with one of the weapons, you take 1d8 necrotic damage before the attack. The damage you take from making attacks with your plasma weapons cannot be reduced or negated by resistance or immunity.
• When you hit a creature with a plasma weapon, it takes an additional 2d8 slashing damage.
• You cannot be disarmed of these armaments but you can dismiss any of them at any time with no action required.
• With no action required, you can instantly summon one or both of these armaments to your hands as long as they are on the same plane of existence as you.
• As a bonus action, you can change one or both of these armaments into another type of armament.
• In the hands of another creature, these armaments lose thier +1 property and become mundane.
• The armamanets last until they are dismissed or until your next short or long rest.
• If you are incapacitated, the armaments are dismissed.
• If the damage you take from making an attack with one of these weapons causes you to fall unconscious, the attack is not made but you still take the damage.

Heartsense

Beginning at 7th level, your attunement with your arcane blood enables you to sense the heartbeats of living creatures. With no action required, you may expend one spell slot of 1st level or higher to focus your senses on the area around you. For 1 hour per level of the spell slot you expend, you can detect the number of beating hearts present within 120 feet

of you. You also know roughly the direction and distance each of them is in relation to you. Your senses can penetrate barriers, but 2 feet of any nonmetal, nonbiological substance, or 2 inches of metal will block your senses.

Additionally, for the duration of the effect, you can attack twice instead of once when you take the attack action, provided you use a plasma weapon for both attacks and you can sense the heartbeat of each creature you attack.

The number of attacks you can make with a plasma weapon this way increases to three when you reach 13th level in this class and to four when you reach 17th level in this class.

Essence Extraction

Beginning at 11th level, you gain the ability to extract the life-essence of your enemies with your plasma weapons. When you hit a creature with your plasma weapon, you can expend one spell slot to deal necrotic damage to the target in addition to the weapon's damage. You regain hit points equal to half the amount of necrotic damage dealt this way and you also gain the same amount of temporary hit points. The extra damage is 1d12 for a 1st-level spell slot, plus 1d12 for each spell level higher than 1st, to a maximum of 4d12 . Constructs and undead are immune to this extra necrotic damage.

Seeker Mastery

At 15th level, you gain one of the following features of your choice.

Heavy Blood. When you hit a creature with a melee plasma weapon that you're wielding with two hands, that creature must succeed on a Constitution saving throw against your spell save DC or be poisoned for 1 minute. If that creature is already poisoned, it must instead succeed on a Constitution saving throw or be stunned until the end of your next turn. The creature can repeat the saving throw at the end of each of its turns, ending these effects on itself on a success.

Torrent of Strikes. When you take the Attack action on your turn, you can expend a spell slot of 3rd-level or higher. If you do, you can make one additional attack with a plasma weapon and if you engage in two-weapon fighting this turn, you can add your Constitution modifier to the damage of the two-weapon fighting bonus attack as long as that attack is made with a plasma weapon.

Vindictive. When a creature hits you with a ranged or melee attack, you can use your reaction to make an attack with a plasma weapon against that creature. You gain a +5 bonus on attack and damage rolls for this attack. Before you make the attack, you can change one or both of your plasma armaments into different armaments with no additional action required.
