Black Blood

School: Hemomancy (Necromancy)
(Intended for use with the School Of Hemomancy subclass)

You toxify your own blood, turning it into a weapon when your enemies harm you. When a creature hits you with a melee attack the creature takes 3d10 acid damage.

If a vampire or blood-sucking creature attempts to use its bite attack against you while under the effects of this spell, your hit point maximum is not reduced and the vampire or blood-sucking creature loses hit points equal to the acid damage dealt to you by the bite attack.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d10 for each slot level above 1st.
