What are Linked Attacks?

When you select a unit and use him/her to attack an enemy, you can trigger a Linked attack as long as there are one or more allies within Attack Range to your target. (up to a max of 3) You can see the participating units in a linked attack on the left side of your selected unit’s portrait in the battle forecast window, before confirming the action.

Linked attacks raise your avoid rate (Avo) and hit rate. If the participating units have Support levels to each other, these boosts are further enhanced, which can also boost your might. (Mt). Units performing a linked attack can also build support to each other.
