Abyssus Abyssum Invocat

You create a 60-foot area around yourself from which 2d12 hands made of pure shadow emerge; this area moves with you. Each hand can attack a target of your choice within the area, and the target must make a Dexterity saving throw. On a failure, a creature takes 10d10 shadow damage and becomes Incapacitated for the next minute, repeating the saving throw at the start of each of its turns to end this Condition.

For each creature you reduce to 0 hit points with this spell, you create 1d6 additional hands and increase the area by 15 feet.
