Tanner's 4E campaign
+1 to AC (On top of the regular chainmail armor bonus, which is +6)
Power (Daily/Healing): Minor action. Until the end of your turn, any character healed by one of your encounter or daily powers gains additional hit points equal to 1d10 + your Charisma modifier.
This chainmail armor belonged to a dwarf paladin during the Old Wars, and has since been in the hands of the Shiniwek Minotaurs.
