Chain Mail +3 (Throne of Bhaal)

Balthazar's Mercenaries Chain Mail is a variant of Chainmail Armor +3 and offers the same amount of protection, an armor class of 2 and the same protection modifiers. This armor appears in Baldur's Gate II: Throne of Bhaal, where it can be gained by killing them. The armor is not enchanted, so it can be worn in combination with rings or a cloak of protection.
