Spelunker Glowstick

The Spelunker Glowstick is a light source that can be held or tossed a fair distance, similar to Glowsticks. However, unlike regular Glowsticks, Spelunker Glowsticks additionally highlight the location of nearby treasures in a 30 block radius around the glowstick with a slight yellowish glimmer. They are purchased from the Skeleton Merchant for each.

Tips

 * While the very similar effect of the Magic Lantern is permanent and does not require holding an item in the hotbar, its radius is smaller than the Spelunker Glowstick.
 * Since all treasures are highlighted with the same yellow glimmer, regardless of value, the Spelunker Glowstick becomes less useful as the game progresses. The Spelunker Potion will be more effective as it does allow differentiating different kinds of treasure.
 * For some reason, spelunker glowsticks do not seem to be consumed when held if you hold them from your inventory menu with autopause off. This allows a small stack of 10-15 glowsticks to last nearly indefinitely as long as you don’t accidentally use them up, basically providing free treasure detection. (Probably a bug; hasn’t been tested on Xbox/mobile yet)

Trivia

 * The Spelunker Glowstick seems to have been made out of a bone.
 * It seems to be more bouncy than a regular Glowstick.
