Death

This spell kills creatures. Roll 8d10; the total is the number of hit points this spell can affect. Creatures within 20ft. of you, yourself included, are affected in ascending order of their current hit points.

Starting with the creature with the fewest current hit points, each creature affected by the spell immediately drops to 0 points and begins to die. Subtract each creature's hit points from the total, before moving onto the creature with the next fewest hit points. A creature's hit points must be equal to or less than the remaining total for that creature to be affected. Once this process can no longer affect any creatures, you lose hit points equal to the remaining total. Undead and creatures immune to necrotic damage aren't affected by the spell.

At Higher Levels: When you cast this spell using a spell slot of 8th level or higher, roll an additional 2d10 for each slot level above 7th.
