You have taken a Sacred Vow to refrain from marriage and sexual intercourse.
Prerequisite: Sacred Vow.
Benefit: You gain a +4 perfection bonus on will saving throws against charm and phantasm spells and effects.
Special: To fulfill your vow, you must abstain from any sexual contact with any other creature. If you intentionally break your vow, you immediately and irrevocably lose the benefit of this feat. You may not take another feat to replace it. If you break your vow as a result of magical compulsion, you lose the benefit of this feat until you perform a suitable penance and receive an Atonement spell.
