Every chest in Mythril Arena is opened on our servers using the tables below. This page lists the complete contents and drop chances for each chest, including the ones you can buy with Mythril in the in-game shop.
How you got a chest does not change what is inside it. A Golden Chest earned in Mythril Trials and a Golden Chest bought in the shop roll from exactly the same table. Coin amounts are drawn uniformly at random across the stated range — every whole number in the range is equally likely. Each chest is rolled independently: previous openings never change the chances of the next one, and there are no pity timers or guaranteed-drop counters.
Chest contents
These are the four chests in the game. You can earn them in Mythril Trials and from the Battle Pass, or buy them in the shop for the Mythril price shown.

Which chest a Mythril Trials stage awards
Clearing a Mythril Trials stage awards one earned chest. Which chest you get depends on the stage number.
| Stage | Wooden | Silver | Golden | Legendary |
|---|---|---|---|---|
| 1–10 | 85% | 13% | 2% | 0% |
| 11–20 | 60% | 30% | 9% | 1% |
| 21–29 | 35% | 40% | 20% | 5% |
| 30 | 0% | 0% | 0% | 100% |
Stages 21 and above also carry a separate 25% chance to drop 5 Mythril on top of the stage chest. This roll is independent of the chest roll.
How to read these tables
- Percentages within a single column add up to 100%. A chest always awards coins, and always resolves its key and Mythril rolls, even when the result is "none".
- Coins, Keys, and Mythril are rolled independently of one another inside the same chest.
- Ranges are inclusive of both endpoints. "300–750" means every whole number from 300 to 750 is possible, each with the same chance.
- Chest openings are resolved by the game server, not on your device.
- Buying a chest does not improve its contents. Paying Mythril gets you the chest sooner, not a better roll.
