Full Plate Mail +2 is enchanted and it offers an armor class of -1 and the usual armor class against specific kinds of physical damage. It has a weight of 50 lbs, which means it's lighter than Full Plate Armor, but heavier than Full Plate Armor +1. It still requires 15 strength to wear it. This item appears in Baldur's Gate II: Throne of Bhaal. It's dropped by Gromnir Il-Khan in Saradush when he meets the party. He thinks the party are assassins sent by Melissan.
Full plate armor is the best armor a warrior can buy, both in appearance and protection, and the enchantments on this suit are particularly powerful. The intricate engraving and spectacular embossing adorning the suit are of indeterminate origin, as is the armor itself.
