Try things out until you beat him. If you can't, train until you are a higher level, than try again.
Look at what the abilities do and figure out a strategy with them.
The only move Baron has that is a problem is Tick Tock, btw. AS long as you can figure out a way to prevent that, or stop it from damaging you, hammering down his Health is a piece of cake. Not to mention he uses Holy Scars at some point, which lowers his defenses drastically and if he ever runs out of Focus, he casts a spell which restores his focus at the expense of some of his health each turn.
i didn't use the "hacks" as you call them until I beat the game. i do it with every game, beat it, hack it, get bored, stop playing. it is not a "hack" but a program that edits flash programs. You seem to have a big mouth for someone that knows so little.
no it doesnt hack it, it EDITS the files that are saved onto your computer when you make a save game, theoretically you would be able to just find these files yourself and bring them up in wordpad and edit the large list of code, but that would take a very long time. this simply just helps by narrowing it down to specific values that you can change then save, and it changes that long line of text script, thus altering the game. just like you would mod your favorite game, say morrowind, if you had the elder scrolls construction set, it would just narrow down all the values that are put into the script and put into a way that is most conveniently editable.
