Earn the opportunity
Win a legendary rift fight. After returning from the arena, select the offered fusion. Winning a rift supplies a bond opportunity for each player; it is not a permanent account upgrade that makes every slot fire.
Choose compatible attacks
The player fusion logic requires at least two single-move slots initially and caps each linked slot at four moves. The source does not exclude buffs from these slots; remember that a buff provides its effect rather than direct damage. Joining one existing slot to another frees a slot. Extend a bond by adding a separate attack when the interface allows it.
Use the result
Switch to the bonded slot during combat. Its attacks can run together, while attacks in your other unbonded slots remain inactive. Mix a crowd-clear pattern with a boss-focused pattern when your legal move pool supports it; our planner helps you check the ingredients, not predict a win.
