Offers a floor-based weekly reward target for players who want to claim Lunacy without extending a run solely for another floor.

WHERE & HOW TO FARM
Where to farm
Backdoor > Mirror Dungeon; follow the active run to its reward claim screen.
Mirror Dungeon weekly rewards depend on how far the run reaches. A Floor 4 claim may be a shorter stopping point when it meets the Lunacy reward condition shown in the current client; it should not be treated as interchangeable with a full clear. Floor thresholds and bonus details are subject to the active mode and season, so read the reward panel before entering and again before claiming. This method is a weekly reward route, not an unlimited Lunacy farm.
Have a weekly bonus reward available if pursuing the limited bonus payout.
Field a team capable of reaching Floor 4 in the selected mode.
Open the active Mirror Dungeon and inspect its weekly reward conditions.
Confirm that the displayed Floor 4 reward includes the Lunacy you are targeting.
Check how many bonus claims remain and choose the mode your roster can clear safely.
Enter with a team prepared to win clashes and handle the displayed enemy affinities.
Clear each floor carefully, replacing or supporting the team only through available in-run options.
Reach Floor 4 and inspect the reward claim before confirming it.
Claim if it matches your goal, then stop rather than continuing only for an unrelated floor.
Farming tips
Use the current in-game reward panel to confirm Lunacy and Pass payout; older reward tables may not apply.
If you need the full Pass reward, check whether Floor 5 is required before stopping.
Repeat, collect and use
Repeat only within the available weekly bonus claims and any currently displayed eligibility. It is not an uncapped Lunacy route; first-clear and story rewards are separate, limited sources.
Common mistakes
Promising yourself the full weekly payout from Floor 4: verify the exact partial reward shown.
Going beyond Floor 4 by habit when only the displayed claim matters: stop once the chosen reward is secured.
Assuming the reward condition stays fixed across modes or seasons: check before each run.
When to stop or switch
Stop after claiming the Floor 4 reward if it satisfies your Lunacy goal; continue farther only when the additional displayed Pass or material reward is worth the time.
