Blood Sacrifice

Your wretched blood will be a sacrifice towards the gods of war to smite all who dare to stand near you. When casting this spell, pay any number of hit points and select up to 8 creatures. All targets within range must make a charisma saving throw or take necrotic damage equal to twice the amount of hit points you paid while casting this spell, taking half of the amount of hit points sacrificed on a successful save. Any target that dies from the damage dealt by this spell deflates as if the blood was drained from their body before decaying and brushing away in the wind, leaving a Soul gem in their place. The strength of the Soul Gem varies depending on the strength of the creature. Refer to the Soul Gem page for more details.

Undead creatures, constructs, and creatures that do not have blood are immune to this spell.
