Anakis's Chill Fire

Necromancy/Evocation cantrip

You create a ghostly, skeletal hand in the space of a creature within range. Make a ranged spell attack against the creature to assail it with the chill of the grave. On a hit, the target takes 1d8 necrotic fire damage, and it can't regain hit points until the start of your next turn. A flammable object hit by this spell ignites if it isn't being worn or carried.

This spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
