Your power clings to existence, slowly fading from the world.
Benefit: To use this feat, you must expend your psionic focus. You may cause an instantaneous power that affects an area to persist until the beginning of your next turn. Those already in the area suffer no additional harm, but other creatures or objects entering the area are subject to its effects. A lingering power with a visual manifestation obscures vision, providing concealment (20% miss chance) beyond 5 feet and total concealment (50% miss chance) beyond 20 feet. Using this feat does not increase the power point cost of the power. Powers that do not affect an area cannot be used with this feat.
