Awaken Forest is a monster-only spell which makes all trees in the caster's line of sight deal irresistible damage to you and your allies if you stand adjacent to them, much like the walls in the Slime Pits. This happens each turn that you end standing next to them, and can deal heavy damage over time if you don't make a quick escape. This effect ends immediately when you kill the caster.
