Acid Blast

A blast of caustic acid erupts from your fingers. Each creature in a 30-foot cone must make a Dexterity saving throw. A creature takes 6d8 acid damage on a failed saving throw, or half damage with a successful Dexterity saving throw.

Creatures that fail their saving throw also take an additional 2d8 acid damage at the end of their next turn.

At higher levels: For each spell slot used higher than 6th level, the subsequent damage increases by 1d8.
