Last War Black Market Guide: Best Rewards, Cash Sources & Smart Buying Strategies
2026-07-30

I see the Last War Black Market as a great place to pick up rare rewards before a new season begins. Still, some deals are much better than others. In this guide, I’ll cover how the shop works and how to earn more cash. I’ll also share what I buy and what I skip. If you plan to spend on packs or Gold Bricks, my Last War Purchase Guide is a useful next stop.
How the Black Market Works
The Black Market opens during the four-week Season Celebration event. Each shop page shows six items. One is free. Two are discounted. The other three are sold at full price. You can refresh the selection up to eight times each day. Always claim the free item and buy anything you need before refreshing. The Last War Black Market uses its own event currency instead of diamonds. Any cash left after the event carries over to the next season.

Earn More Black Market Cash
There are several free ways to build your balance. Week one features a bingo board with simple missions. Completing squares and lines earns cash. Finishing the full board gives a larger bonus. During weeks two to four you can earn up to 600 cash per day from activities such as radar tasks and zombie battles. Secret Mobile Squad tasks provide extra cash outside that daily limit. Fireworks and Champion’s Duel predictions can also add to your total. I try to complete every free source because cash goes quickly in the Last War Black Market.
Best Items to Buy
Exclusive Weapon Shard Choice Chests are my top pick. These shards are hard to find and give heroes lasting upgrades. I also look for discounted decorations. Their stat bonuses stay active all the time. Universal Decor Components are useful if your decorations still need levels. Discounted Legendary Blueprints can also be worth the cash. The Last War Black Market is most valuable when you spend on rare items that support long-term growth.
Items You Should Avoid
I usually skip Skill Medal Chests and Valor Badges. Both are easy to collect through normal play. Speedups and resource chests are rarely good deals either. They solve a short-term problem but do little for permanent progress. Dielectric Ceramics are another weak choice once your main squad has enough. The Last War Black Market only lasts for a limited time, so I save my cash for items that are difficult to get elsewhere.
Shop Refresh and Spending Strategy
I always claim the free item before touching the refresh button. The shop can refresh eight times each day. The first refresh is free. Most of the others cost 10 diamonds. The final one costs 30. Every refresh replaces all six items. The Last War Black Market can show the same reward more than once, so I check each new page carefully.
I do not spend cash just because an item has a discount tag. I first ask whether the reward is rare and useful for my main team. I also keep some cash ready for Exclusive Weapon Shards when they appear. Unused cash carries over to the next event. That makes saving a perfectly good option. With the Last War Black Market, patience often brings better value than buying everything in sight.
Conclusion
The Black Market rewards patience more than impulse spending. Claim every free item and complete as many cash tasks as possible. Save your currency for rare upgrades that will still matter next season. A few smart purchases can do far more for your account than a cart full of common materials.
