Balance issues
1 ... If you start with 1 star and continue to 3rd-5th monster -> your chances of winning are 0.
2 ... You are forced to start with 5 stars -> or your chances
3 ... When you win 1st 2 bosses at 5 stars best way to 3rd boss is to farm all stats to 100 (depends on RNG items)
4 ..... best way to play:
4.1 ... max 1 stat
4.2 ... make other stats you dont get 1hit
4.3 ... cause 3rd issue there are items which would 1hit monsters
