Let's say I have a Monk who fights with spiked chains and Kyton style, and has the Vow of Chains to reflect him wearing his chains, even while fighting with them. Would the spiked chains count as his one valuable item from the Vow of Poverty, or would he be able to have another item outside of his chains.
Vow of Chains:
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.
Vow of Poverty:
The monk taking a vow of poverty must never own more than six possessions—a simple set of clothing, a pair of sandals or shoes, a bowl, a sack, a blanket, and any one other item. Five of these items must be of plain and simple make, though one can be of some value (often an heirloom of great personal significance to the monk). The monk can never keep more money or wealth on his person than he needs to feed, bathe, and shelter himself for 1 week in modest accommodations. He cannot borrow or carry wealth or items worth more than 50 gp that belong to others. He is allowed to accept and use curative potions (or similar magical items where the item is consumed and is valueless thereafter) from other creatures.
