In some events (like solo conquest), it is advisable to have a low spirit cost team in the early level so you can take out as much demon bosses as possible since they are weak. However, the game chooses your team automaticall (mostly your top 10 ATK/DEF demons) which costs alot of spirit naturally. The only thing you coud do is choose a 1* demon as your lead (which I did) to save spirit cost and kept changing to higher 2*/3* untill you reach a point where you must all your maxed demons to take out the boss.
