🛡️ Event Overview

The Cosmic Battle is a thrilling cross-server PvP event where players clash using their current hero rosters. Before the battles commence, a 24-hour Hero Ban Phase allows the community to vote out specific heroes, adding a strategic twist to team compositions. Banned heroes are marked with a lock icon and cannot be used in either attack or defense teams during the event.

Battle Mechanics:

  •  Manual or Auto Battles: Choose to control your heroes manually or let the AI handle the combat.
  • Skip Option: Skip battles to see immediate results, though this forfeits manual control advantages.
  • Retry Feature: If you lose a battle, you have the option to retry for Emeralds, preserving your win streak if successful.

⚔️ How to Participate

  1. Set Up Your Defense Team:
    Navigate to the event interface and assemble your defense lineup. Ensure none of the banned heroes are included.
  2. Engage in Battles:
    After setting up your defense, you can search for opponents of similar ranking. Each battle consumes one attempt, which regenerates every hour. Additional attempts can be purchased with Emeralds.

Official Rules

General Information

The Cosmic Battle is a cross-server event where players battle each other using their Heroes at their current power.

Players advance to higher-tier leagues by earning ranking points. The higher you get, the greater your victory reward and the final event reward.

Special Feature

You can pick any of your Heroes except for the ones voted out by the community. The banned Heroes have a lock icon on their avatars. Those characters are excluded from the lineup for the duration of the event – for attack and defense.

Joining the Event

To participate in the event, you need to assemble a defense team. Matchmaking will become available once you do that. To set up your defense team, press the “Defense” button.

Defense

Once you have set up your defense team, you are officially part of the event and other similarly ranked players can attack you.

Attacking

To start a battle, press the “Find” button. You will get matched with an opponent of a similar ranking. Press “Attack” to assemble your attack team and enter the battlefield.

Win Streak

Win streaks net you an additional prize. As you rack up more wins, your win streak level goes up along with the value of the extra reward. Win streak resets when you lose a battle.

For each three wins a row a player receives 200, 400, 600 and 800 Cosmic Battle Points for the first (x1), second (x2), third (x3), and fourth (x4) streak or 3, 6, 9 and 12 consecutive wins, respectively. The fourth streak (x4) is then repeated for as long as the player keeps winning.

Retrying a Battle

If you have lost a battle, you have the chance to make a comeback by pressing the “Retry” button. In that case, your win streak will not end you will not go down in rankings (unless you will lose again in the retry, of course).

Rewards

All battle rewards and the final ranking rewards include Cosmic Battle Coins that you can spend in the event shop.

The top 50 players get extra coins and unique avatar frames.

Additional Rules

Attempts

Each player starts with five battle attempts per day. The number goes down with each attack not including retry’s which do not count as additional battle attempt. Players can get one refill per hour for a total of 23 additional attempts during a day. Additional attempts can be purchased starting with 300 Emeralds for 5 attempts; increasing with each purchase, and being reset the next day. During the first Cosmic battle there also was an “Unlimited Attempts” option (for real money instead of Emeralds).

Reward for Successful Defenses

Players are rewarded 200, 240, 280 or 320 Cosmic Battle Coins per successful defense depending on their “Win Streak” (x1-x4). These coins are sent to the player’s Mail(box). Initially, there was a reward limit for five succesful defenses per day, however, this limitation has been removed since the second or third edition of Cosmic Battle.

Leagues

Battle other players and earn ranking points to advance to higher-tier leagues and divisions. The seasonal reward scales with your (league and) division.
