Easter Event - Mar 31 - Apr 21
Resurrection Event - Arena Battles have “The first time each Hero would die, they Resurrect to full Health.”.
Fight Against the Multitudes Mode - Face off against infinite Noble enemies that become stronger every time an enemy dies. You have 5 minutes and 4 additional reinforcements to kill as many Nobels as you can. The more enemies defeated the bigger and better your rewards.
Each battle you play adds your score to the leaderboard, as you compete against other players over the course of the event to see who can have the highest amount of kills and the highest rewards.
