Preparations
You may use 1 squad for this battle. Leaders are locked to Summoners and all Summoning Pedestals are available. Element Mastery restrictions are still in place so plan accordingly to defeat the foes ahead. You are allowed 1 item set for the entire challenge. There is no cooldown when using a friend. 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.
