You can charge your melee weapon with additional damage potential.
Prerequisite: Str 13.
Benefit: To use this feat, you must expend your psionic focus (see Concentration skill description). Your attack with a melee weapon deals an extra 2d6 points of damage.
You must decide whether or not to use this feat prior to making an attack. If your attack misses, you still expend your psionic focus.
