Forming your Teams[]

The first thing to do in the Lost Battlefield is form your teams. The Lost Battlefield's team edit interface is similar to the Lost Realm’s interface. You must form your teams before you can fight in the Lost Battlefield. You’ll need to form three teams of up to five Heroes each. No Hero can be repeated across all teams. After deploying your Heroes, tap ‘Save’ and you’re done!

There are up to three rounds in a Lost Battlefield match. The battle process is the same as that of the Lost Realm. The Lost Battlefield employs a best-of-three play style, so all you need to do is win two rounds to win the battle. Lost Battlefield Rewards: There are two types of rewards in the Lost Battlefield, the Challenge Rewards and Season Rewards.

  • Challenge Rewards: You’ll win Season Points and Fame from each battle in the Lost Battlefield.

The amount of Season Points and Fame you earn for winning a battle depends on your opponent. If your opponent has more Season Points than you, you’ll earn more Season Points.

For example: You currently have 200 Season Points. If your opponent has 300 Season Points, you’ll earn 38 Season Points when you win the battle. If your opponent has only 100 Season Points, you’ll earn 22 Season Points for winning the battle. Losing the battle will always grant you 10 Season Points. If you don’t have any Fame bonus, the Fame you earn will be equal to the Season Points earned.

Season Points:[]

Season points

 These are the points earned in battle. They reset after every season. The more Season Points you have, the more Gems you’ll earn at the end of the season.

There are five different ranks based on the amount of Season Points earned. They each provide a different bonus to the Fame earned from battles.

Rank 1 1 - 299 0%
Rank 2 300 - 599 10%
Rank 3 600 - 999 20%
Rank 4 1000 - 1499 30%
Rank 5 1500 + 50%
  • Fame
    Fame: Fame is earned when you challenge opponents in the Lost Battlefield. They can be used to buy items from the Warehouse. Your rank in the Lost Battlefield will affect the amount of Fame you’ll earn from each battle. Higher ranks will grant a greater bonus.
  • Season Rewards: When the Season ends, you’ll earn Gems based on your total Season Points and Rank position. For example: If you're first in Rank 2 with 599 Season Points, you’ll win 200 Gems. The higher your ranking, the more rewards you’ll win).

Note: If two players have the same amount of Season Points, the first to win the amount will be ranked higher.

The amount of Gems Gem awarded based on rank and position is as follows:
