Arena Mode (Replacing Guardian Mode)
Starting 29th June, The Arena will be replacing Guardian Mode.
Once you reach 5,000 honor, you'll be given the option to join The Arena. You can only achieve at most 5,000 honor from regular multiplayer attacks. Achieving more than 5,000 honor can only be done in The Arena. If you drop below 4,750 honor, you'll be removed from The Arena. To enter the Arena, you click on "The Arena" battle map indicator. You cannot loot gold or gain rings during Arena attacks, however you may have the chance to win both from the Arena Chest after each victorious Arena battle. Unlike Guardian Mode, you will not lose honor at the end of each day in The Arena. This will make the Honor leaderboard (player & Kingdom) far more competitive! You can still do regular Multiplayer attacks after you've entered The Arena. You can loot gold and win rings in regular multiplayer, however you won't be able to win or lose honor! You do however, still lose honor in defense. Winning and losing Arena battles does not affect your row streak in regular multiplayer attacks.
You'll be given the option to attack up to 3 different bases of varying difficulty. You'll see a 5 minute timer, if you do not start an attack within that time frame, you'll be matched with different bases again.
The easiest battle costs 4 Battle Stones to attack - the least risk, but also the least honor gained. You'll lose the most honor for a failed attack.
The medium battle costs 3 Battle Stones to attack - average risk, average honor gained.
The hardest battle costs 2 Battle Stones to attack - the most risk, but the highest honor gain. You'll lose less honor for a failed attack.
You can scout each of the bases before deciding which one to attack. When you're inspecting the enemy base, you can press the left and right arrows on the side to toggle between the 3 bases.
After every victorious Arena battle, you'll be presented with an Arena Chest.
What you can win from the Arena Chest:
Exclusive Epic Ancient: Zillah (New Spell Tower Ability: AoE Confuse)
50+ Rings
Epic Battle Boosts
Epic Ancients
Battle Stones
250,000 gold
Diamonds
