When you cast this spell, you mark a fixed surface with an arcane inscription, occupying a 5-foot diameter circle. When a creature enters the glyph's space or otherwise disturbs it, the glyph triggers.   You can refine the trigger by specifying or exempting creatures or creature types, or by specifying a password a creature can speak as a reaction to prevent the glyph from triggering.   The glyph is nearly invisible and requires a successful Intelligence (Investigation) check against your spell save DC to be found. A creature has advantage on this check if it is able to perceive magical effects, such as by casting detect magic. If a creature uses its action to destroy the glyph, or the surface is destroyed, the spell ends without triggering.   As part of the casting, you must cast another prepared spell of 3rd level or lower, storing it in the glyph. The spell must have a casting time of 1 action and must be able to target a creature other than the caster. When the glyph triggers, it releases the stored spell, targeting the triggering creature. If the spell targets an area or summons creatures, the effect is centered on the triggering creature. A spell requiring concentration lasts for its full duration. A triggered glyph glows brightly for the stored spell's full duration. If a creature uses its action to destroy the triggered glyph, or the surface is destroyed, the spell ends.
