Psychic Rush
(Magic of Eberron, page 51, DnD 3.5)
[Psionic]
You can occasionally manifest a psionic power with less effort.
Benefit
When you manifest a power, you can spend an action point to reduce the power point cost of that power by 1d6 power points, to a minimum cost of 1 power point. The cost of the power before the reduction cannot exceed your manifester level.
