you get insane drops. if you are going hard on the event, that's the time to spend pots. heck, i made profit while spending pots during my fever time.
i used up 6 half pots, for a total of 291 stamina refilled.
during fever time i got 12, 10stamina pots. 2, 30stamina pots and 1, 50 stamina pot for a total of 230 stamina back. 2 gold medals. lots of extra points and quite a bit of gatcha points in that time frame. you will get fever time in all types of events, raid boss, towers and arena. this is the time you go hard because you will get bonuses.
since i'm pretty comfortable with my pot count. i think ill aim for 150th place or 1 tier below. i just want an SR ticket out of this. don't want the actual event card.
