SRD:Power Specialization

Power Specialization [Psionic]
You deal more damage with your powers.

Prerequisites
Weapon Focus (ray), manifester level 4th.

Benefit
With rays and ranged touch attack powers that deal damage, you deal an extra 2 points of damage. If you expend your psionic focus when you manifest a ray or a ranged touch attack power that deals damage, you add your key ability bonus to the damage (instead of adding 2).
