Grants another action, Atk/Spd/Def/Res+3, and the "unit can move to a space adjacent to any ally within 2 spaces" status to adjacent ally with the highest HP for 1 turn. (Allies with Sing or Dance can be granted this effect as well. If multiple units meet the conditions, effect will not trigger.) (Duo Skills can be used once per map by tapping the Duo button. Duo Skills cannot be used by units deployed using Pair Up.)
Standard Effect 1: Duel
If unit is 5★ and level 40 and unit's stats total less than 190, treats unit's stats as 190 in modes like Arena. (Higher-scoring opponents will appear. Stat total calculation excludes any values added by merges and skills.)
Grants another action to target ally. Grants Atk/Spd/Def/Res+3 and the following status to target ally and allies in cardinal directions of unit and target (excluding unit): "Unit can move to a space adjacent to any ally within 2 spaces." (That turn only. Cannot target an ally with Sing or Dance. This skill treated as Sing or Dance.)
