Acid Rain (EFA - A)

You create a 20-foot-radius, 40-foot-high cylinder centered on a point within range. Until the spell ends, a downpour of pure acid fills the cylinder.

When a creature enters the spell's area for the first time on a turn or starts its turn there, that creature must make a Constitution saving throw. The creature takes 5d8 acid damage on a failed save, or half as much damage on a successful one.

The ground within the area becomes muddy and/or slick from the downpour, and for the duration becomes difficult terrain.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th.
