Ebon

A Hellblood Sorcerer thrusts their hand forward, black veins momentarily bulging as a chilling, spectral claw of pure void energy erupts. The air around them grows noticeably colder, and a faint, guttural snarl escapes their lips as a demonic chill invades their own bones, momentarily overwhelming their senses with alien malice. If the spell misses, a phantom, searing pain might shoot through their dominant arm, as if a shard of their own blood-magic has been ripped away, leaving a lingering, unpleasant emptiness. You create a ghostly, skeletal hand in the space of a creature within 120 feet. Make a ranged spell attack. On a hit, the target takes 1d8 necrotic damage, and it can't regain hit points until the start of your next turn. If you hit an undead target, it also has disadvantage on attack rolls against you until the end of your next turn. The damage increases to 2d8 at 5th level, 3d8 at 11th, and 4d8 at 17th.
