Blood Corruption Aura.
Prerequisite: Bloodcraft, level 16.
- You can use your action to emit a deathly aura of necrotic energy that causes the veins of nearby foes to burst and bleed. For 1 minute, any hostile creature with blood that moves within 30 feet of you for the first time on a turn or starts its turn there takes 3d6 necrotic damage. If a hostile creature with blood regains hit points while in the aura, it regains only half as many hit points as expected.
- Once you use this feature, you can’t use it again until you finish a long rest.
