 The Fusion attack is launched by tapping the partner pin on screen; the player then has a limited period to complete card-based minigames to build up a damage multiplier.For example, with Shiki as their partner, the player is shown one Zener card, along with a number of other Zener cards that are shown face-up for a moment before being turned over.The player must select those face-down cards that were matches for the shown Zener card.
