Wisp in a Bottle

The Wisp in a Bottle summons a wisp, a ghostly face surrounded by blue fire, to provide light. It serves much the same purpose as the Shadow Orb or the Fairy Bell, but the wisp not only keeps pace with the player, it actually moves ahead in the direction the player is moving. This can be used to see a short distance through walls. It cannot be used together with the Shadow Orb, and summoning either will dismiss the other.
