Body armor

Body armour is armour work on the body; big surprise. The two most valued varieties are mithril in the early game and dragon scale mail until the Ascension. Neither one 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 armour is dragon scale mail. For 40 weight, it reduces your AC by 9, provides a useful intrinsic, 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.
