Spelunker Potion

The Spelunker Potion is a buff potion that grants the Spelunker buff when consumed, which illuminates valuable nearby objects. The highlight color varies between versions.

It has a small chance to appear as a bonus drop from Slimes.

The Spelunker buff illuminates the following objects:
 * Ores
 * Gems
 * Pots
 * Herbs
 * Dye plants
 * Chests
 * Life Crystals
 * Life Fruits

Treasure colors
On all versions but the, ore and other treasures will be displayed with a yellow tint. This will somewhat alter the natural color of the highlighted treasure, such as making Cobalt turquoise and Orichalcum red. Some ores are not affected, these being Crimtane (unlike its counterpart Demonite), Meteorite, Obsidian, and Hellstone. Meteorite and Crimtane, however, do provide their own light.

In the, every type of ore will be displayed in a specific color and will glow and flash:
 * has a reddish tone.
 * is red and blue, flashing.
 * has a blue shade.
 * looks like copper, but with a slight yellow tint.
 * is hard to distinguish from silver. Since it always gives off a glow, Spelunker is not needed to search for it.
 * is an intense blue, making it very distinct.
 * looks like silver, only the texture is slightly different and has a hint of green.
 * is like copper but darker and more red.

Tips

 * The Metal Detector informs the player of nearby treasure. This can help the player determine when there's nearby treasure worth spending a Spelunker Potion for.
 * The effect of the Spelunker Glowstick is similar to that of Spelunker Potions, but they have the advantage that the player is able to mine and perform other actions at the same time.
 * Spelunker Potions are best used while playing in high-resolution displays.
 * They are very useful for finding rarer ores in Hardmode.
