The shaman causes a creature within 30 feet to spark and shimmer with electrical energy. Though this effect does not harm the creature, it does cause the creature to emit light like a torch, preventing it from gaining any benefit from concealment or invisibility. Furthermore, while the aura lasts, whenever the target is hit with a metal melee weapon, it also takes an amount of electricity damage equal to the shaman's Charisma bonus. The sparking aura lasts 1 round for every 2 shaman levels the shaman possesses. A creature affected by this hex cannot be affected by it again for 24 hours.
