Vow of Peace

 
Prerequisite(s): Sacred Vow, Vow of Non-Violence
 
Benefit: You are surrounded by a 20' radius calming aura. Creatures in range must make a will save vs DC = 10 + 1/2 Char level + Cha bonus, or be affected as if by a Calm Emotions spell. You gain a +2 natural armor bonus, a a +2 deflection bonus and a +2 exaulted AC bonus. The exaulted bonus does not apply to touch attacks. To fulfill your vow, you cannot cause harm or suffering to any living creature. You may never do real damage or ability damage, although you may deal subdual damage. If you leave a helpless foe to be slain, you have broken your vow. If you break your vow, you lose it forever and do not get a new feat to replace it. If you break the vow due to magical compulsion, you lose all benefits until you attone. Creatures that take the Vow of Peace have been known to drink water through a filter so as to not accidently drink and thereby harm a small insect.
