Chill Touch - Necromancy

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 damage, and it can't regain Hit Points
until the start of your next turn. Until then, the
hand clings to the target. If you hit an Undead
target, it also has disadvantage on Attack rolls
against you until the end of your next turn.
This spell's damage increases by 1d8 at 5th, 11th,
and 17th l
