This spell creates the equivalent of field plate mail around the caster (AC2). The field plate appears to be composed of living flames. It sheds lights as a torch but does not shed heat. The spell lasts until the caster his hit in melee. When the caster is hit in melee, the attacker is burned for 1d6 damage plus 1 point per level. The spell then ends. Otherwise the spell lasts for 3 rd/level. The material component is a piece of metal that has been magically heated.
