Amayui Labyrinth Meister:Unions

About Unions
Unions are a new mechanic where two units can occupy a single tile as a main unit and support unit pair. This should be familiar to those who have played Fire Emblem games featuring the Pair Up mechanic.

Moving allied one unit on top of another forms a Union with the moving unit acting as the support unit. Movement is then dictated by the main unit, which is determined by the selected unit and can be switched at any time. The main unit can be switched at any time, including after the pair have taken all actions. When the main unit's actions are expended, the union can no longer take actions for that turn.

Unions can be leveled by engaging in actions that grant character EXP, up to a maximum of 5. This will increase the stats granted by the Union and can also unlock new skills. Character-specific unions also feature active union skills, with Character 1 using Skill 1 and Character 2 using Skill 2. These active skills will upgrade to their omega (Ω) version at Union Level 5.

Generic Unions
Generic Unions are special in that any two units who meet the requirement can benefit from the effects. In addition, the Union EXP gained for each Generic Union applies to any units capable of benefitting from that specific Generic Union.

For example, if Mikshuana and Flare Harpua were in a Union and leveled up the Fire Pact Union, other fire units such as Kisnir will benefit from that leveled up Union later on.
