Brimstone Rain

Globs of smoldering brimstone erupt from the earth, dealing 8d6 fire damage to each creature in the area with a basic Reflex save and choking them with sulfurous fumes. For the duration, the area is difficult terrain, and breathing creatures that start their turn in the area must succeed at a Fortitude save or take (the item's level − 3)d6 persistent poison damage; this is an inhaled poison effect. On a critical failure, they're also Sickened 1. You can Dismiss the spell.
