Gemstone



Gemstones are one of several Artifact currencies that can be found within the Underworld. They can be used to commission upgrades at the House Contractor. It's currently the bottom tier artifact in the "trade up" tree.

Obtaining Gemstones

 * Chamber Rewards : Blue Laurels chambers can give Gemstones as Bounty, with three possible amounts depending on the type of room. Normal Rooms give 5 Gemstones, Hard Rooms give 10  Gemstones. Blue Laurels chambers will be more common when Bosses drop their bounty instead of  Darkness.
 * Infernal Troves : Once purchased from the House Contractor, some rooms will contain an Infernal Trove which sometime contains Gemstones. Infernal Troves are challenges where the player must slay foes quickly to claim a bigger part of the reward. The troves can be upgraded to contain more Gemstones, from 25 to 50  and finally 75, for a total investment of 660.
 * Fishing : Selling fishes caught in Tartarus and Styx to the Head Chef rewards with gemstones based on the rarity of the fish. The common fish are of little value compared to the rare ones, making the easy mastery of the fishing minigame a reliable entry of Gemstones.
