Inscribes a delicate but particularly potent acid, cold, electrical or fire glyph not far from the caster's feet, unseen unless discovered with a DC 25 Search check. Any caster may have only one glyph active at a time - inscribing another will cause any active glyph to dissolve harmlessly. Once scribed, any creature other than the caster which trips the glyph causes the entire area to erupt with the selected elemental energy, dealing 2d8 selected elemental damage/2 levels (max 8d8). A glyph behaves like a supernatural trap and may be disarmed by anyone with the trapfinder feat with a DC 32 Handle Device check, else the glyph explodes.
