You can empower your ranged attacks, sending them farther.
Prerequisites
Benefit
As long as you maintain psionic focus, the range of your ranged weapons increases. When you use a projectile weapon, such as a bow, its range increment is doubled. When you use a thrown weapon, its range increment is tripled. This benefit doesn’t stack with the benefit of Far Shot.
In addition, you may expend your psionic focus as part of a ranged attack (but not a ranged touch attack) to ignore any penalties for range increment for that single attack. That attack still has its range doubled or tripled as if you were maintaining psionic focus.
Special
With the Far Shot feat (a prerequisite of this feat), your range with projectile weapons is increased by one-half, and your range with thrown weapons is doubled.
