While upgrading a card with Dust boosts its stats up to Level 5, fusing two Level 5 copies of the same card unlocks a special Fuse Ability. This ability does not enhance the card's Attack or Defense stats but can significantly impact the outcome of a battle.
Fuse Abilities can include enhancements such as increasing attack or defense, healing damage, gaining an extra orb in combos, reflecting damage, or bypassing an opponent's defense.
To Fuse a Card:
-
- Upgrade: Choose "Upgrade Cards" from the Main Menu.
- Select Card: Cards at Level 5 eligible for Fusion will be marked as "Fusion Available." After selecting the first card, a second Level 5 card will be automatically selected for Fusion.
- Fuse: The "Fuse Cards" option will appear at the bottom of the screen. Confirming this choice will combine the two cards into a single Fused card, granting it the Fuse Ability.
