Treasure Chests in Paladins are a way to try your luck to get random rewards, or rare, epic and even legendary Cosmetic Items. The treasure chest menu can be accessed from the in-game store.
To open a chest, simply select the chest you want, and then click the "Open Chest" or "Purchase" button. Most chests can only be opened with Crystals, but some of them can be unlocked with Gold and VIP Points. Chest rolls are also awarded as rewards for certan quests.
Some chests, such as the Gold Chest and Diamond Chest, allow the opportunity to unlock directly purchasable content at a fraction of its original price.
