Restriction: The monk must abstain from all sexual and intimate physical activity. A monk with this vow takes it to an extreme, refusing to even share a room with another person, or sleeping on the opposite side of a camp from other people in a group. A celibate monk is not allowed to touch others or have others touch him (including touch spells from allies). Striking enemies in battle or being struck by enemies is not prohibited, but the monk shuns all peaceful or pleasurable contact.
Benefit: A monk with this vow increases his ki pool by 1 ki point for every 5 monk levels (minimum +1).
