RPG Insanity

So I managed to get to Stella and Franz Lab but I couldn't beat her mostly due to not having all humans riding with golems (all but lock) were decimated before I could reach said battle so all humans had the strongest equipment you could buy at the white radish HQ but even then I was not able to kill Stella so what would be a good set up of golems and human equipment to beat her as I'm already ticked that I couldn't stop her Regen factor and all characters were lvl 99  pls help if ya can

I have same issue. I am only level 94,94,93 and 94. Vales loses his golem ages ago and thanks to the lazy scumbag programmers that did not put in the machine that lets you get back your golem in one of these pointless rooms they have you run through.

then you have yet another boss with auto regen that can be used multiple times while I can only use mine once. By far the worst pile crap I have played. I am done with kemco games.
