The Arena is the competitive PvP mode where you pit your best team against other players' teams. Your score is determined by the strength of your units (stats, merges, skills) and how many KOs you achieve without losing any units. Higher scores lead to higher tiers and better weekly rewards, including Orbs and Hero Feathers. Arena Assault is a more challenging variant where you must use a different team for each of seven consecutive battles. Building a diverse roster is essential for success in Arena Assault.
