WHERE & HOW TO FARM
Gem Mine passive gem production
Bastion > Gem Mine.
Before you go
- Have access to the Bastion and its Gem Mine interface.
- Have the Gems required by the current unlock or upgrade screen if you choose to invest.
- Know which account purchase or resource goal you are saving Gems toward.
Farming steps
- Open the Gem Mine in the Bastion and inspect its current unlock or upgrade requirements.
- Compare the displayed cost with your other near-term account priorities.
- Unlock or upgrade the mine only when you can afford the investment without compromising a more urgent need.
- Allow its passive production to accumulate while playing other activities or while away.
- Return to the Gem Mine and collect available Gems as the interface permits.
- Track your Gem balance against a planned purchase or resource goal.
- Use the collected Gems through the in-game option that best supports that goal.
- The mine generates passively, so it can contribute while you focus Energy on Campaign, dungeons, or other content.
- The initial investment is substantial; consider the long-term production against your immediate needs.
Repeat, collect and use
Passive and ongoing after unlocking; collect accumulated Gems when available. Production is limited by the game’s current mine rules and capacity shown in the interface.
Common mistakes
- Spending the unlock cost without checking current account needs; compare it with other available uses first.
- Forgetting to collect available production; revisit the mine periodically.
- Spending Gems without a goal; decide what account need the balance should support.
When to stop or switch
Keep the mine as a passive source after unlocking; stop further investment when the displayed upgrade cost is less valuable than another account priority.
