The Mystery Supply Box is a randomized reward chest obtained through the Secret Command Post in Last War Survival. It can contain resources, recruitment tickets, Skill Medals, Gear Material Chests, Drone Components, and extremely rare premium rewards. This guide explains how to earn Mystery Supply Boxes, their listed drop rates, and how to use the rewards efficiently.
What Is the Mystery Supply Box?
The Mystery Supply Box is connected to Secret Tasks and alliance assistance at the Secret Command Post. Completing eligible tasks or helping allies with their missions can provide boxes that contain one reward selected from the available drop table.
Most boxes provide standard progression resources. However, every box also has a small chance of containing rare items such as recruitment tickets, a Universal Legendary Hero Shard, an Epic Decoration Chest, or 5,000 Gems.
The contents are determined randomly. Opening more boxes gives you more opportunities to receive a rare reward, but it does not guarantee a particular item.
How to Get Mystery Supply Boxes
The Secret Command Post is the main source of Mystery Supply Boxes. Players can earn them through two related activities:
- Complete Secret Tasks: Finish eligible missions available through the Secret Command Post.
- Help alliance members: Assist allies with their Secret Tasks when support opportunities are available.
The number of boxes you can earn depends on the tasks available, how actively you complete them, and how often you assist alliance members.
Tips for Earning More Boxes
- Check the Secret Command Post daily: Complete available tasks before they refresh or expire.
- Join an active alliance: More active members can create additional opportunities to assist with missions.
- Respond quickly to support requests: Available assistance slots may fill before every alliance member can join.
- Complete higher-value tasks: Prioritize useful Secret Tasks based on their direct mission rewards as well as the Mystery Supply Box opportunity.
- Claim completed rewards: Check the Secret Command Post after finishing a task so rewards are not left uncollected.
Mystery Supply Box Rewards and Drop Rates
The table below shows the listed items, rarities, and probability of receiving each reward from one Mystery Supply Box:
| Item | Rarity | Chance to Obtain |
|---|---|---|
| Trade Contract | Legendary | 2.00% |
| Legendary Recruitment Ticket | Legendary | 0.25% |
| Survivor Recruitment Ticket | Legendary | 0.25% |
| Universal Legendary Hero Shard | Legendary | 0.10% |
| Secret Order | Legendary | 1.00% |
| 5,000 Gems | Epic | 0.01% |
| Epic Decoration Chest | Epic | 0.10% |
| Resource Chest | Rare | 83.94% |
| 150 Skill Medals | Rare | 1.00% |
| 100 Upgrade Ore | Uncommon | 2.50% |
| 10 Gems | Uncommon | 1.00% |
| 50 Gems | Uncommon | 0.10% |
| 20 Gear Material Chests | Uncommon | 4.75% |
| x5 5-minute Speedup Chests | Uncommon | 2.00% |
| Level 1 Drone Component Chest | Common | 1.00% |
Important Note: The listed probabilities total 100%. However, these rates come from current community-documented game information rather than an official publisher webpage. Check the reward preview inside the game in case a future update changes the available items or probabilities.
Understanding the Drop Rates
The Resource Chest has an 83.94% probability, making it the expected reward from most Mystery Supply Boxes. Rare premium items have considerably lower probabilities.
For example, the listed chance of receiving 5,000 Gems is 0.01%. This is equivalent to a one-in-10,000 probability for each independent opening, but it does not mean the reward is guaranteed after opening 10,000 boxes.
Similarly, the Universal Legendary Hero Shard and Epic Decoration Chest each have a listed probability of 0.10%. Opening a large batch increases the number of attempts, but every individual box still follows its own random result.
Common Progression Rewards
Although rare rewards attract the most attention, common rewards provide the majority of the Mystery Supply Box’s practical value.
- Resource Chests: Support building upgrades, research, troop training, and other account development.
- Gear Material Chests: Provide materials used in the Gear Factory.
- Upgrade Ore: Supports equipment enhancement and hero gear progression.
- Speedup Chests: Reduce waiting time for selected construction, research, training, or healing activities.
- Drone Component Chests: Support Drone development through the Component Factory and related systems.
Rare Recruitment and Hero Rewards
Recruitment tickets and Universal Legendary Hero Shards have low drop rates, but they can support long-term hero and survivor progression.
A Legendary Recruitment Ticket is used through its corresponding recruitment system. A Survivor Recruitment Ticket is used to recruit survivors rather than combat heroes, so the two tickets should not be treated as interchangeable.
Universal Legendary Hero Shards are generally most valuable for developing eligible Legendary heroes. Avoid spending them without deciding which hero should receive the upgrade.
Should You Open Boxes Immediately or Save Them?
Saving Mystery Supply Boxes does not improve the listed probability of receiving rare rewards. Opening 100 boxes together and opening the same 100 boxes separately provide the same number of individual chances under the listed drop system.
Opening boxes immediately may be better when:
- You need resources for an upcoming building upgrade.
- You need Gear Materials, Skill Medals, or Upgrade Ore now.
- Current progression is being delayed by a lack of basic resources.
- You prefer to use rewards as soon as they become available.
Saving boxes may be useful when:
- You prefer opening a large batch at one time.
- Your inventory already contains enough resources for current upgrades.
- You want to track the results from a larger sample.
- You are waiting to confirm whether a future event specifically rewards opening chests.
Do not save boxes based on claims that a particular day or opening method improves rare drop rates unless the game explicitly states that such a bonus is active.
How to Use Mystery Supply Box Rewards
The best use of each reward depends on the systems currently limiting your progress.
- Resource Chests: Keep them unopened until you need resources for a planned upgrade, especially when protected inventory is safer than exposed resources.
- Skill Medals: Focus on important skills used by heroes in your primary squad.
- Upgrade Ore: Invest first in gear equipped by your strongest and most frequently used heroes.
- Gear Material Chests: Use them as part of a planned Epic or Legendary Gear crafting path.
- Speedups: Save them for long upgrades or events that reward construction, research, training, or healing.
- Gems: Review the best ways to spend Diamonds before using a large premium-currency reward.
- Drone Components: Combine lower-level components according to your main Drone progression needs.
- Recruitment Tickets: Use them in the correct recruitment system rather than assuming every ticket recruits combat heroes.
Common Mystery Supply Box Mistakes
- Expecting rare rewards regularly: Most openings will provide Resource Chests because they have the highest listed probability.
- Believing a rare reward is guaranteed: Probabilities describe individual chances, not a guaranteed result after a fixed number of boxes.
- Ignoring common rewards: Resources, materials, Ore, and speedups provide consistent progression value.
- Spending rewards without a plan: Rare materials can be wasted when spread across too many heroes or systems.
- Using recruitment tickets incorrectly: Hero and survivor recruitment tickets belong to different systems.
- Saving boxes because of unverified drop-rate rumors: Hoarding does not change the listed probability for each opening.
- Missing alliance support opportunities: Helping active alliance members can provide additional chances to earn boxes.
Mystery Supply Boxes and Account Progression
Mystery Supply Boxes provide a mixture of common resources and low-probability premium rewards. Their main long-term value comes from consistent Secret Task completion and alliance participation rather than depending on one rare opening.
Building a large inventory of resources, recruitment items, gear materials, and Drone Components can require months of regular activity. Players who prefer to begin with established inventory and account development can explore a Last War Survival account for sale through Heaven Guardian. Available accounts may include developed heroes, upgraded buildings, accumulated materials, and progressed combat systems, with lifetime warranty coverage and premium support for a safer purchase experience.
