Glyph of Imprisonment

5th-level abjuration

Casting Time: 1 minute

Range: Touch

Components: V, S, M* (a platinum coin, which the spell consumes)

Duration: Until triggered or dispelled

When you cast this spell, you inscribe a glyph on the wall of a room or chamber. You can designate any number of creatures that you can see when you cast this spell to not trigger this glyph.

The glyph can cover an area no larger than 10 feet in diameter.

The glyph is nearly invisible and requires a successful Intelligence (Investigation) check against your spell save DC to be found.

Any creature other than the ones you designate that pass through the entrances to this room and remains inside for 10 seconds triggers the glyph, creating an invisible but impenetrable barrier made of force that prevents creatures from passing in or out of the room at any entrance. Nothing can physically pass through the wall.

It is immune to all damage. A disintegrate spell destroys the wall instantly. The wall also extends into the Ethereal Plane, blocking ethereal travel through the wall.

This wall lasts for 24 hours, at the end of which it disappears and releases any creatures trapped within.
