Mines of Divan

The  is a location in the Crystal Hollows more specifically the Mithril Deposits, where the Jade Crystal can be obtained. Claiming the crystal requires a Scavenged Emerald Hammer, Scavenged Diamond Axe, Scavenged Lapis Sword, and a Scavenged Golden Hammer.

Talking to the Keeper of Lapis, the Keeper of Gold, the Keeper of Diamond, or the Keeper of Emerald gives the player a Metal Detector. The Metal Detector, while held, shows the player's distance from the treasure, rewarding either one of four Scavenged Items, Mithril / Gemstone powder or Gemstones. The crystal will appear in the center after delivering each scavenged item to their respective keepers.
