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 or Gemstones. The crystal will appear in the center after delivering each scavenged item to their respective keepers.
