Oneiric Mire
Ground across a battlefield behaves like sinking mud, slowing crossers and threatening to root the unlucky in place until they see through the trick.
You shroud an area in illusory dreamstuff, making the ground look and feel like a deep mire or quicksand. Ground in the area is difficult terrain.
Each creature in the area when the spell is cast, or that enters the area, must attempt a Will save. On a failure, it believes it's being pulled down by the earth, taking a -10-foot circumstance penalty to its Speeds. On a critical failure, it's also Immobilized. In addition to the normal actions to Escape, at the end of an affected creature's turn, it can attempt a Will save, removing the effects on a success. On a critical success at any Will save made against oneiric mire, the creature fully disbelieves the illusion and no longer needs to make Will saves to risk a Speed penalty or being immobilized, though the area is still difficult terrain.
