You can conjure your powers into existence with blaring thunder or fearful shrieks, deafening creatures damaged by their effects.
Benefit: To use this feat, you must expend your psionic focus. You can modify a power to deafen a creature damaged by the power. When a creature takes damage from this power, it becomes deafened for a number of rounds equal to the level of the power. If the power allows a saving throw, a successful save negates the deafening effect. If the power does not allow a save, the target can make a Fortitude save to negate the deafening effect. If the power effect also causes the creature to become deafened, the duration of this metapsionic effect is added to the duration of the power. Using this feat increases the power point cost of the power by 2. The power’s total cost cannot exceed your manifester level. Powers that do not inflict damage cannot be used with this feat.
