The caster creates a small, magical zone that can detect the passage of enemy creatures. When the field is activated, it explodes, doing 1d8 points of sonic damage per two caster levels to all creatures within the area of effect up to caster level 10 and then an additional 1d8 points of sonic damage per 4 caster levels thereafter. After being triggered, the glyph dissipates.
