Xaddus' Liquid Barrier

This spell forms a barrier around the targeted creature by which air and solids may pass freely to and from the target, but liquids may only pass from the target. thus, while in effect, the targeted creature will stay dry in pouring rain or when  underwater. The target is also impervious to acid, lava, or other damaging liquids. They are not protected, though from the heat generated by the lava. Magical liquid may pass through the barrier if the spell fails a savign throw.
