When the player or an ally member activates their Unison, a Unison Chance will occur. Certain combinations of Unison can make a Unison Attack occur. During a Unison Chance, all allies with a completely filled Unison gauge can tap the UNISON button on the bottom of the screen to join the Unison. After tapping the UNISON button, players can choose from up to the first five Monster Gear equipped to initiate or assist in the Unison Chance. Each Monster Gear does a different Skill when called for a Unison Attack; these can be found by viewing the Monster Gear's Encyclopedia entry or by viewing them from a player's inventory.
