Restriction: Either out of penitence or to bring attention to the suffering of the
enslaved, the monk wears shackles on his wrists and legs. This gives the
monk a –1 penalty on attack rolls
and to AC, and reduces his movement by 10 feet. If temporarily unable
to wear his chains, he may carry rocks or some other heavy burden
(including medium or heavy armor) to simulate this suffering.
Benefit: A monk with this vow increasing his ki pool by 1 ki point for every 3 monk levels (minimum +1).
