(Combat)
Your powerful fists can reduce undead foes to dust.
Prerequisites
Channel Smite,
Improved Unarmed Strike, base attack bonus +9, channel positive energy 4d6.
Benefit
On a confirmed critical hit using an unarmed strike against an undead creature, you can expend two uses of your channel energy ability as a
Swift Action to destroy that undead creature. The undead creature can negate this effect with a successful Will saving throw (DC = 10 + your base attack bonus).
