Deny Passage

Level: 4
Duration: 1 minute
You force an area to deny access to a group of creatures specified by your utterance. Crimson bars ward the area you name. 
If your Truespeak check is successful, you can forbid creatures from entering the area of the utterance. Unless you allow a creature inside the area (an immediate action on your part), it is held at bay just outside the place as if affected by a protection from evil spell (although for this utterance, the alignment of the creature doesn’t matter). Reddish prison bars appear briefl y to block the creature’s path, then disappear when the creature stops trying to enter the utterance’s area. The bars are intangible to everyone else, and the affected creature can’t interact with them in any way. You likewise prevent creatures from leaving the truenamed place. Unless you allow a creature to leave (as an immediate action), it is held at bay at the boundary of the area, stymied by the reddish prison bars.
