Your arcane strikes can pierce the veil of the beyond.

Prerequisites: Base attack bonus +3, Arcane Strike.

Benefit: When you make a successful melee attack or a ranged attack against an incorporeal creature with a weapon imbued with your Arcane Strike feat, your attack deals 75% damage instead of the standard 50% damage.
If you expend your Arcane Strike’s duration as part of the attack, your attack deals full damage. You must decide whether or not to use this option prior to making an attack. If your attack misses, you still expend the duration. Your weapon or natural weapon actually appears to become briefly incorporeal as the attack is made.

Note: This feat was initially published by Dreamscarred Press (Ultimate Psionics, pg. 102; “Ghost Strike (Psionic)”), but has been edited for use with the pathFinal Fantasy ruleset.
