As a standard action, you can transform your body into pure life energy, resembling a golden-white fire elemental. In this form, you gain the elemental subtype and give off a warm, welcoming light that increases the light level within 10 feet by one step, up to normal light. Any undead creature striking you with its body or a handheld weapon deals normal damage, but at the same time the attacker takes 1d6 points of positive energy damage + 1 point per oracle level. Creatures wielding melee weapons with reach are not subject to this damage if they attack you. If you grapple or attack an undead creature using unarmed strikes or natural weapons, you may deal this damage in place of the normal damage for the attack. Once per round, if you pass through a living allied creature's square or the ally passes through your square, it heals 1d6 hit points + 1 per oracle level. You may use this ability to heal yourself as a move action. You choose whether or not to heal a creature when it passes through your space. You may return to your normal form as a free action. You may remain in energy body form for a number of rounds per day equal to your oracle level.
