I THINK I REACH THE INFINITE LOOP :D
Check this stats guys:
MY BOY MUDGILL ( look the damages at the right side)
The thing is: synergies are very important. Tactician is incredible, it gives a lot of speed. Magical makes abilities like mudgill's take away insane. And above all, bulky is stupid, it's giving me stats of 999 on almost all monsters.
I can still improve the builds more, but I think I'm at a point where I'm going to get +999 on all monsters and the enemies don't get much stronger anymore. I'll tell you where I ended up or if I really managed to reach the infinite loop.
Sorry for my bad english.
