The subject of the spell is surrounded with an invisible aura that delays the teleportation of any creature within the spellfs area seeking to leave it. Any teleportation spell or effect (including all spells with the teleportation descriptor) are delayed. The spell delays the departure of the teleporting creature by 1 round (so that it departs on its initiative count immediately before its next turn).

GM Note

The BoXM entry is for players playing in the Arcane Age of Greyhawk campaign. It is based on Monte Cook's Book of Experimental Magic. I cannot recommend it enough.
