Battle Chest contain mystery rewards including resources, gold, and exclusive honor items. Every 24 hours the player starts with 9 locked chests, which may have higher or lower value depending on the day and what chest the player chooses. On the right of the chest are icons telling the player which value chests are available that day. On different days there might be Silver Chests (level 2; at least 2), Gold Chests (level 3; at least 1) and Royal Chests (level 4). The rest are always the low value Wooden Chests (level 1). After 24 hours chests reset, and the player gets a new batch of chests.
Battle Chests are unlocked using Keys, which can be won in battle. The player can earn 2 keys each battle, one for destroying 20%, and another for destroying 60%. Each key unlocks one battle chest.
Players can access Battle Chests by clicking the icon in the bottom left of their screen, above the attack and defense log.
