The caster imbues an iron bead strung on a thong of ox hide with magic energy. While the bead is worn, the caster gains a +4 bonus to his Armor Class and damage reduction of 15/+5. Once 10 points of damage per caster level have been prevented, the spell ends and the bead becomes a normal object again. The spell is negated if the thong and bead are removed.
