Raid Shadow Legends – Ally Join Attack is a skill in Raid Shadow Legends that allows some or all of your allies to join with the Ally Attack champion and attack using their default A1 ability. Ally Attack is an excellent way of gaining more attacks without taking more turns. It is most commonly used in 3 areas:

1. Blender Arena Team – Utilises strong AoE A1 champions such as Skullcrown and Sinesha. You’ll most likely use Arbiter to provide an increase attack and your 2nd champion will be an ally attacker.
2. Fire Knight – An excellent way to break the Fire Knight shield especially if you bring multi hit A1 champions
3. Clan Boss – Increase your damage output by bringing an extra attack (plus if you rely on A1 debuffs this is a greater chance to maintain these on the clan boss)
