Void Slash

You channel pure void through your blade and unleash a 70ft dimensional slash. Each creature in the area must make a Constitution saving throw. A creature takes 10d10 force damage and 10d10 slashing damage on a failed save, or half as much on a successful one. On a failed save, the creature is also banished to a harmless void pocket until the end of your next turn.

This damage ignores resistance to slashing or force damage. Creatures normally immune to either type have resistance instead for this spell.
