Ebon

Arcane Scholar gestures with precise, almost robotic movements, and a skeletal hand, formed from pure, cold shadow, coalesces with chilling exactitude. The air around them becomes perfectly still and frigid, a testament to the sterile application of forbidden necromantic formulae. The scholar's expression remains detached, focused only on the efficient transfer of life force. If the spell fails to hit, the scholar might experience a momentary disassociation devoid of warmth or meaning, a common side effect of delving too deeply into The Other Place's cold logic. 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.
