Weapon and Armor Proficiency: Apostles of peace gain no proficiency with any weapon or armor.
As part of their sacred vows, apostles of peace forswear the use of armor, though they may wear magic items that protect them (such as a ring of protection or bracers of armor). An apostle of peace who wears any armor is unable to cast apostle of peace spells or use any of his supernatural class abilities while doing so and for 24 hours thereafter.
yet their vow of poverty requirement says they can't use any magic items. so, just a couple to start off with ^^;
