Abyssal Impact

Infuse your arm with abyssal magic to form tentacles that lash out at your foes. Each creature in a 15-foot cone must make a Dexterity saving throw. A creature takes 5d6 bludgeoning damage on a failed save, or half as much damage on a successful one. If the target fails their saving throw they are drenched in abyssal ink until they use an action to remove it. A target covered in the ink takes an additional 1d6 necrotic damage when they are damaged by an attack.

In addition, if you currently have any Cruxes the spell consumes all of them and deals an additional 1d6 bludgeoning damage per Crux used.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2snd.
