Acid Rain

A torrent of acidic rain begins to pour down within a 20-foot-radius, 40-foot-high cylinder centered on a point you choose within range.

Each creature who enters or starts their turn in the area must make a Dexterity saving throw. On a failed save, a creature takes 8d8 acid damage and is inflicted with the poison condition until the end of its next turn. On a successful save, the creature takes half damage and is not inflicted with the poison condition. This spell turns the selected area into difficult terrain for the duration of the spell.

You can dismiss the spell early as a bonus action.
