Body armor

Body armor is armor worn on the body; big surprise. The two most valued varieties are mithril in the early game and dragon scale mail until the Ascension. Neither of these can be corroded or otherwise damaged, and they provide an excellent AC reduction for their weight; the only problem is that mithril impedes spell casting.

Dragon scale mail

The single most valued item of body armor is dragon scale mail. For 40 weight, it reduces your AC by 9, provides a useful intrinsic (depending on the color of dragon it came from), and does not corrode or impede spellcasting. The two most coveted varieties are gray dragon scale mail, which provides magic resistance, and silver, which gives reflection.
