Wisp in a Bottle

The Wisp in a Bottle is a post-Plantera Hardmode item used to summon a light-providing "wisp" that follows the player. It serves the same purpose as the Shadow Orb or the Fairy Bell, but the Wisp is brighter and keeps better pace with the player, actually moving ahead in accordance with the direction keys the player is pressing.

The Wisp in a Bottle is a rare drop from Blue Armored Bones, Hell Armored Bones, and Rusty Armored Bones (0.25% or 1/400 chance, or 0.375% or 3/800 chance in Expert Mode).

It cannot be used together with any Light Pet, and summoning any will dismiss the present. It cannot be Reforged.

Trivia

 * Wisp may refer to Will-o'-the-wisps, mythological creatures that lead travelers to their death in swamps.
 * It is the only "in a Bottle" accessory which cannot be used to double jump or craft a balloon.
