Spell: Corrosive Muck

Area all squares in two @Template[burst|distance:10]{10-foot bursts}.

You create two puddles of acidic slime that hinders the movement of anyone who walks through them. The area of each pool becomes greater difficult terrain. Each round that a creature starts its turn in one of the pools or enters a pool during a move action it's using, it takes 8d6 acid damage with a basic Reflex save. A creature that critically fails its saving throw also takes 1d6 acid,persistent. As normal, if a Large or larger creature starts its turn in both pools, it takes the damage only once.

Heightened (+2) Create an additional 10-foot burst.
