Wall of Coral

6th-level conjuration

Casting Time: 1 action

Range: 120 feet

Components: V, S, M (a handful of coral shards)

Duration: Concentration, up to 10 minutes

This spell functions as wall of thorns, but creatures damaged by a wall of coral must also take a DC 16 Constitution save or take 1d4 poison damage and be poisoned. Poisoned creatures must repeat the saving throw each round of its turns. On each successive failed save, the character takes another 1d4 damage and continues to be poisoned, on a successful save the poison ends providing they are no longer touching the wall of coral.

Druids or other creatures with the ability to pass through undergrowth unharmed can pass through a wall of coral without harm. A wall of coral created outside of salt water has a maximum duration of 1 minute.
