Recurring challenge rewards
Dark Zone Purification periodic rewards
Dark Zone Purification is a recurring challenge with periodically refreshed objectives and rewards for account progression.
Battle > Challenges > Dark Zone Purification.
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.
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.
