Chests can be found at the end of a dungeon or in Battle Royale Mode. After you open a chest with your sword of other weapons, you will usually receive 1-3 diamonds by different dungeons of coins and a chest bag. There are usually Potions or even Ultrarares in the chest bag. Chests in dungeons of King Mode seem to take a lot of time to close again. Sometimes, there are some bats or rats guarding the chest at the last of the dungeon. Be careful because they may kill you because you may have low health after fighting a lot of mobs.

Trivia
