📖 To increase a hero's resonance, you will need a copy of that hero.
What to do:

1. Tap the helmet icon to access the Hero Collection.

2. Tap on the card of the hero whose resonance you want to enhance. Then tap on Resonance at the bottom left.

3. In the window that opens, on the right side of the screen, you will see the Attune button. Tap on it.

4. To enhance the resonance of the selected hero, you can use a copy of a hero. Select the hero copy you want to spend.

5. To deselect, click on the selected hero icon again.

6. Once you've selected the copy, press Attune to enhance the hero's resonance.

Important: if you use a leveled-up hero to enhance the resonance of another hero, you will get back:

• all equipment worn by the hero you use: it will be transferred to the inventory

• all jade spent on improving their skills
