Wartskin

A variant of the 2nd level priest spell Barkskin, the recipient of this spell develops a rough, knobby covering over his body similar to a toad. This lowers the base AC of the recipient by 2 plus 1 point for every 3 levels of the caster. In addition, the recipient receives a +2 to saves versus attack forms which are physical in nature. This spell does not function with armor or any other form of magical protection.
