Pathfinder: Legacy of Fire
Once affixed, this ancient ankh bonds seamlessly to the hilt or handle of any magic melee weapon. The ankh’s power remains dormant until you fall in battle— unconscious, dead, or dying. At that point, the ankh animates the weapon, enabling it to strike out against all foes, tenaciously guarding your fallen body. Treat this effect as a dancing weapon, except that the weapon is allowed to make up to three attacks of pportunity each round. The ankh tirelessly defends you for up to 1 hour or until you regain consciousness. The ankh can only be activated once per day.
