Preparation
You may use up to 3 squads and 1 item set for this battle. Each of the squads must have unique units in them and you are allowed up to double your total cost. You can select a different friend from your entire friends list for each squad that you can bring in. There is no cooldown when using a friend to fight against the enemies. Your items do not get replenished when a team dies, so bring as many healing items, elemental seals, BB gauge support items, Revive items, and status cure items for paralysis/curse as you can for this fight.
