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

The Gold Extractor and Aggregator themselves 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 or Aggregators as you wish (up to 100).

Large Packs contain 6 of the parts needed to assemble a Gold Extractor. Gold Aggregators can be blended using Gold Extractors.

Each slot has the following probabilities:
Common: 20%, Rare: 40%, Epic: 25%, Legendary: 15%

This drop can only be claimed using WOMBAT tokens. WOMBAT is available here
