WHERE & HOW TO FARM
Where to farm
Battle > Challenges > Dark Zone Purification.
Dark Zone Purification updates at intervals, so its useful farm is the set of challenges and rewards actually available in the current cycle. Enter from Challenges, read the stage objective, and claim the listed reward after completing it. Because the source material does not establish the exact current reward contents or a stable route, use the in-game display to select challenges that match your roster and needs.
Check the currently available challenge list and reward display.
Build a team suited to the selected stage objective.
Open Battle > Challenges > Dark Zone Purification.
Read the available challenge objectives and inspect their listed rewards.
Choose a stage that offers a reward you want and is within your team’s capability.
Select Modifiers and equipment appropriate to the displayed objective.
Complete the stage and claim the rewards the client shows.
Review the remaining current-cycle challenges and repeat for any still-useful reward.
Farming tips
Use the exact mode title in the client; do not assume similarly named hazard content shares its reward rules.
The available objectives can change, so plan from the active list instead of relying on an old rotation.
Repeat, collect and use
This is a periodic mode rather than a fixed permanent stage farm. Complete useful challenges during the active rotation, claim each reward, and revisit when the mode updates. Collect and spend rewards through the relevant in-game progression screens.
Common mistakes
Assuming a specific item is always available: verify the current reward panel.
Confusing Dark Zone Purification with another hazard mode: enter the named activity and follow its own objective.
Leaving rewards unclaimed after a clear: return to the reward track and collect eligible items.
When to stop or switch
Stop after claiming the rewards that matter in the current cycle, or switch to Nightmare Recurrence if its displayed upgrade materials better suit your immediate need.
