Combination is the process by which most higher grade heroes are obtained.


To be able to Combine or Evolve heroes, a few requirements must be met:

  1. Two heroes of the same grade.
  2. Both heroes must be level 30.
  3. Both heroes must have an Upgrade level of +7.

Once these requirements are met, you can access the Combine/Evolve screen, which can be found on the right-hand side of the stats screen for one of the heroes. Upon entering the Combination screen, you'll see two slots on the left for the heroes to be combined, the left slot filled with the hero used to enter this screen and the right slot empty. On the right side, you'll see a list of all heroes eligible for Combination with this hero. Select the one you wish you use as material.


Some things about combination should be noted:

  • Like with Upgrading, if a hero being Combined is equipped with anything, that equipment will be lost if it is not removed before Combination.
    • If a hero is equipped with something, a notification will appear above the hero when it is selected to warn the player.
  • Combination is free. Evolution cost 150 Rubies.
  • Combination and Evolution never fail.
  • Combination and Evolution only produce a hero one grade higher than the ones used as materials.
    • Evolution will produce a hero one grade higher in the same line as the one used as a base.
  • Contrary to popular belief, Combination always produces a random hero.
    • This may or may not exclude Devils.
