Endless
Endless sends your team into a continuous chain of battles. Every defeated enemy is replaced by another, and the Run continues until your Heroes can no longer fight.
Your goal is to build as much Total Damage as possible before the Run ends.

How a Run Works
Damage dealt to every enemy is added to the same Total Damage score. This makes Endless different from Campaign: one quick victory is not enough. Your team must survive multiple fights while continuing to deal reliable damage.
You receive 3 Attempts. Each Attempt starts a new Run and gives you another chance to reach a higher Total Damage result.
Rewards and Progress
Each Endless Level has 5 Damage Milestones. Reaching a milestone earns its reward; collecting all five completes the Level.
Every Tier contains 5 Levels. Complete them all to reach the next Tier, where the Damage requirements become more demanding.
You do not need to reach every milestone in a single attempt. Use later Runs to improve your result and collect rewards that were just out of reach before.
Building an Endless Team
Strong opening damage helps, but endurance is just as important. Heroes who can survive, recover, protect teammates, or keep dealing consistent damage become more valuable as a Run continues.
If your team falls early, look at which Heroes dealt the most damage and which ones struggled to stay alive. A different lineup, better Equipment, or one Hero upgrade can carry the next Run much further.
Progression Tip
Prepare your team before spending an Attempt. Claim Campaign rewards first, make the upgrades you can, and then see how many new milestones that extra strength can unlock.
