This potion is most useful when you use it with full screen. This way, it shows many more ores than it would otherwise be showing in windowed mode. This is more useful in jungle or corruption biomes, as they have more ores than others. However, many ores look the same, so make sure you aren't actually looking at worthless Copper Ore, instead of rare Adamantite Ore. Hellstone is the only ore that is unaffected by Spelunker Potions, this is probably because Hellstone is always close to lava and is self-illuminated.
- An easy way to distinguish Adamantite ore from copper ore is the Adamantite's more violet appearance, as opposed to the copper being more of a red.
- It is recommended to use a Spelunker Potion and fly/grapple along the roof of the underworld to find any of the 3 hardmode ores, especially Adamantite Ore, because they can be found in abundance at that depth.
- The Spelunker Potion is arguably the most expensive potion, due to the non-renewable Gold Ore that it requires.
- It also appears to highlight Bound NPC'S.
