Hell's Park

In this area, there are 70 stages, each with a clear reward. The progress of clears will be reset after a fixed period of time (each month) and the rewards can be obtained again. From the currency you get from clearing stages, you can draw from the hell park gacha.

Stage 41 ~ 50

Enemy Battle Speed 15,000 [Enemies take 80% reduced Magic Damage.]

A strong physical attacking team is best. Magic should really only be used when gaining more press turns or when there are stat bonuses involved.

Having a Speedster demon of some sort is a great boon to keeping up with the fast Enemy Battle Speed.
