This game can already be completed with VxD's sol, just tested it and it works.
But I just messed around in the fights a bit a found this, as stated above HP = 4b*1 this goes for Energy too.
To gain constant counterattack, search for 0, gain counterattack, search for the % value of the counterattack and you should have just a few results, if not, get attacked and search for 0. Change the value to whatever you want, freeze it and you always have counterattack (the icon won't show though). Same goes for defense.
The rage meter is a bit different, every two bars of rage is 256 to a max of 1280 at full rage. So search for 0 when you have no rage, gain 2 bars of rage(3 combined rage-gems), search for 256 if not found directly gain rage and search for 512 , change value to 1280 and freeze it. You now have unlimited rage and it will execute at the end of your turns.
Hope this helped somebody to mess around a bit!
