( Complete Psionic, p. 64)

[Metapsionic]

Psionic powers you manifest that utilize negative energy are branded with an imprint of fear.

Prerequisite

Stygian Archon (CP) , know two powers that utilize negative energy,

Benefit

To use this feat, you must expend your psionic focus. You can alter a stygian power that deals negative levels to toes so that any living creature that gains a negative level as a result of the power also becomes shaken for 1 minute. The target of a stygian power can attempt a Will save at the power's save DC (even if it doesn't normally allow a save) to resist this effect. This is a mind-affecting fear ability. Creatures immune to fear are not immune to the primary effect of the power, but they are immune to the shaken effect. Using this feat increases the power point cost of the power by 2. The powers total cost cannot exceed your manifester level.
