Wall of Dissolution

Tier 1 Epic conjuration

Casting Time: 1 action

Range: 120 feet

Components: V, S, M (a vial of fresh acid from a black dragon)

Duration: Concentration, up to 1 hour

A vitriolic wall of slick acid appears on the ground, forming a semi-transparent barrier up to 90 feet long, 30 feet high, and 5 feet thick, centered on a point you can see within range.

Alternatively, you can shape the wall into a hemisphere up to 30 feet in diameter centered on a point you choose within range. The wall remains in place for the duration.

Creatures in the wall’s area when it is created, who move into the wall for the first time on their turn, or who start their turn within the wall must succeed on a Constitution saving throw or take 12d8 acid damage, or half as much on a success. If a creature fails its saving throw by 5 or more, it takes double damage from the spell. A creature attempting to move through the wall must spend 4 feet of movement for every 1 foot moved.

At Higher Levels. When you cast this spell as a tier 2 Epic spell or higher, you may increase the wall’s thickness by 10 feet per tier above tier 1.
