Battlefields

Arenas are unique battlegrounds that are unlocked as you increase your Trophy count. Each Arena, besides the final Arena: Legendary Arena, will unlock new Cards. You receive more rewards like Cards and Gold in Chests with a higher Arena level. Except for the Legendary Arena, players can go 50 trophies lower than the promotion requirement of the same Arena without being demoted to the previous Arena (e.g. You have to get to 300 trophies to be promoted to Bone Pit, but as long as you stay above 250 trophies, you will not be demoted back to Goblin Stadium).

Unlockables
Certain features are unlocked when the player reaches new Arenas rather than Experiencelevels.
 * Goblin Stadium (Arena 1) unlocks TV Royale and Shop.
 * Bone Pit (Arena 2) unlocks the ability to gain Mega Lightning Chests from winning battles.
 * P.E.K.K.A's Playhouse (Arena 4) unlocks the ability to gain Epic Chests from winning battles and Shop offers. Legendary Chests also begin to show up as Shop offers at this Arena.
 * Spell Valley (Arena 5) unlocks the Fortune Chest's ability to guarantee "Daily Fortune" Cards.
 * Royal Arena (Arena 7) unlocks the ability to gain Legendary Chests from winning battles. It also upgrades the King's Chest to the Legendary King's Chest, which guarantees one Legendary Card and adds the feature to choose one card between two.
