Increase in star ranking means that the Hero could be leveled up further, which in turn directly influences their main stats — Attack, Defense and Health. Therefore, fusing allows to increase the Power of Heroes.
Any Heroes with star ranking of 4 to 9 can be fused. Maximum star ranking for a Hero is 10.
Pick a Hero you would like to Fuse and tap the star button in the top right corner.
Fusion required a number of copies of the designated Hero with different star ranking as well as a couple of any other Heroes of certain star ranking but same element.
It's really easier than it sounds, so let's check the example of fusing Angel of Mercy from 4-stars to 5-stars. You will need the following:
- Angel of Mercy 4-stars, the designated Hero you want to fuse
- 3 additional 4-star Angels of Mercy
- 3 additional 3-star Angels of Mercy on top of that
- And finally, 4 additional 4-star Heroes of the same element - Light
Please note that all 10 additional Heroes are considered to be a resource for the process, so they will be gone after the fusion is complete.
Tip: It's not obligatory to level up a Hero to a current maximum in order to increase their star ranking.
If you have enough additional Heroes a red marker will appear on the corresponding icon.
Tap on each icon, pick Heroes you would like to use and tap the Confirm button. After all additional Heroes would be chosen, the Fuse button would unlock, so tap on it to increase the star ranking of the designated Hero.
If additional Heroes would be missing at the time being, tap on Find Heroes to find out where you can obtain Heroes required for fusion. Here are several examples:
- Summon Heroes using Hero Shards.
- Use Basic or Royal Summoning Scrolls to try and receive a required Hero at the Summon Gate.
- Use Summoning Spheres to try and receive a required Hero at the Elemental Gate.
- Use Magic Dust to exchange your current Heroes in the Laboratory.
Tip: We recommend purchasing all available 3-star Hero Shards using Gold in the Kingdom Shop every day. This way you will always have a solid supply of 3-star Heroes required for fusing. Kingdom Shop refreshes every 24 hours.
The basic method of increasing the star ranking from 6 to 10 is the same, mostly you will require 5-star and 6-star Heroes. If you would like to check how many additional Heroes you already have for fusing the designated Hero we recommend visiting the Temple of Power.
Temple of Power
While in the Temple of Power you will see that each Hero will have a percentage number under their icon, which means how many additional Heroes you currently have for a successful fusing. Therefore, 100% means that you increase the star ranking of this Hero right now.
The Temple of Power is located in the Hero Academy that can be built after you upgrade your Castle to level 6. Also, Temple of Power could be accessed from the Trainer tab in the Heroes menu.
Process of fusing in the Temple of Power is almost identical to fusing in the Heroes menu. The only difference is that while in the Temple of Power you will have to manually choose a Hero first.
Fusing 6*-10* Heroes
The basic method of increasing the star ranking from 6 to 10 is common for all elements. Increase of the star ranking from level 7 to level 10 can only be done in the Heroes menu.
6* > 7*:
7* > 8*:
8* > 9*:
9* > 10*:
