Inscribes a delicate but deadly 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 be occluded by fell energy, dealing 1d6 negative energy damage/level and bestowing deathwatch for 3d3+1 rounds. Targets who already have deathwatch must make an additional death save or else collapse. No effect on unliving targets. 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.
