It was tactical at beginning and then quickly become a solving-puzzles-in-two-turns kind of game.

Mini Boss character deals so much damage that there is no way your regular characters even with best gears plus immunity could survive a fight without loss --- just throw in some grass substitution instead is probably a better bet.

So instead players put the champions in and try to rush the boss down. Why? because Champions recovers in three turn even if they died.

I cleared chapter 4 with a lot of grinding, and that is about it. The enemies just hit so extremely hard.
