Fusing Requirements Chart

Fusing is a special technique in SOULS that lets you combine two or several heroes to make one hero even more powerful. When you fuse heroes, it boosts the star level of your chosen hero, which, in turn, makes their Attack, HP, and Defense stats go up.

You’ll be able to start fusing heroes once you’ve progressed to chapter 2 in the game.
