WHERE & HOW TO FARM
Where to farm
Backdoor > Mirror Dungeon > current season mode; inspect the season’s theme-pack and gift unlock information before starting.
The current Mirror Dungeon season has season-specific content, including theme packs and gifts that support a run’s build. Explore the active dungeon and use its in-game unlock information to identify which packs or gifts are still unavailable and what progress the client requires. This is a season-bound progression target, separate from claiming weekly bonuses: unlocks expand later run choices, while weekly bonus claims are a limited payout. The active dungeon name and unlock conditions can change with a season, so follow the live mode screen rather than relying on a remembered route.
Have access to the current season’s Mirror Dungeon mode.
Bring a team capable of completing the encounters required by the displayed unlock conditions.
Open the current Mirror Dungeon mode and read its available theme-pack or gift unlock list.
Select an unlock that is still marked unavailable and check the condition shown in the client.
Start the current mode and follow its displayed route and encounter choices toward that condition.
Choose the relevant events or encounters when they appear, using the in-game labels to confirm they match the unlock goal.
Manage clashes and team condition so the run can reach the required point.
Finish the required encounter or run condition, then return to the unlock list.
Confirm the pack or gift is now available before planning a later run around it.
Farming tips
Pursue one visible unlock condition at a time; the current unlock list is the reliable guide to what progress remains.
A newly unlocked pack or gift improves future run options but does not itself replace a weekly reward claim.
Repeat, collect and use
Unlocking a particular pack or gift is a limited progression objective and may be tied to the current season. Explore further only for remaining season unlocks; check the next season’s mode for its own content and conditions.
Common mistakes
Assuming every season uses the same Mirror Dungeon name or unlock requirements: inspect the active season’s client screen.
Entering without a specific unlock condition: identify the target first so encounter choices serve a purpose.
Expecting an unlock to grant weekly bonus rewards: claim those through the separate reward system.
When to stop or switch
Stop once the desired current-season packs or gifts show as unlocked, or switch to weekly bonus runs if their limited claims are still unused.
