With the aid of a necromancer ally, summon a powerful spirit and fashion it with rare darksteel armor. If you can decipher the possessed armor's true name twice and sacrifice 3 symbols, then it can either be summoned for 4 rounds as an entity (that can only be hurt by spells or unique entities) or enhance the attack and reduce the damage taken of an entity by x1.3.
