• Fusion is a feature that uses low rarity Heroes to combine into a new Hero with higher rarity.

  • Fusion has a failure rate. If failed, all Hero materials will be lost.

  • Heroes obtained after fusion will have random skin, stats and skills.


Fusion has 2 types of materials: main and extra materials

  • Main ingredients:

Heroes with rarity lower than your target’s rarity 1 level

There are 4 main material slots.

Must put in at least 3 main ingredients to be able to fusion.

Each main material has a corresponding success rate of 25%.


Using 3 Rare heroes will have a 75% chance to upgrade to 1 Super Rare.

Using 4 Rare heroes will have a 100% chance to upgrade to 1 Super Rare.

  • Extra ingredients:

Heroes with rarity lower than your target’s rarity 2 level.

Increase the fusion success rate.

Different rarity materials will have different increases in success rates.

There is no limit to the amount that can be added, until the success rate is 100%
