Event and upgrade supplies
Underground Purge exchange currency and stock
Spend Underground Purge reward currency on a useful item in the live Global exchange before its displayed stock changes.
WHERE & HOW TO FARM
Underground Purge exchange currency and stock
Fight > Underground Purge or its current event entry for rewards; Shop > Event Exchange > Underground Purge for purchases.
Before you go
- Underground Purge is currently accessible in the game menu.
- The mode shows an available reward or currency objective.
- The live exchange lists an item that helps a current upgrade.
Farming steps
- Open the current Underground Purge entry and inspect available objectives and reward conditions.
- Choose an accessible challenge that you can complete reliably.
- Clear the activity according to its displayed objective and collect the result.
- Check your currency balance to confirm the mode reward was received.
- Open Shop > Event Exchange and select the Underground Purge tab if present.
- Inspect listed items, costs, and the reset or availability text shown in your client.
- Redeem currency for a specific useful item and apply it to its intended progression use.
- Use the Global shop’s live stock and timing labels; do not rely on a remembered rotation.
- Prioritize the exchange item that resolves a current shortage before optional purchases.
Repeat, collect and use
Limited by the mode’s current availability, reward currency, and exchange inventory; the activity and stock can rotate, so repeat only while the client shows an active route.
Common mistakes
- Treating the mode as permanently open: verify its current menu presence first.
- Assuming a twice-monthly reset or fixed stock: follow the timing and inventory shown in-game.
- Entering without a purchase goal: check the exchange before farming so the reward has a use.
When to stop or switch
Stop when the useful live stock is purchased, no more currency is available, or Underground Purge is no longer shown as accessible.
