In order to start mining Gold in Dungeon Master, you'll need a Gold Extractor. The Gold Extractor can be assembled through blends on https://blend.wombat.app/.

The Gold Extractor itself will be stakable in the game and produce a small amount of Gold in each dungeon run. You'll be able to stake as many Gold Extractors as you wish (up to 100).

Medium Packs contain 4 of the parts needed to assemble a Gold Extractor.
