I only took a quick look at it, so it's likely I could be wrong about this, but it seems all the important processing is done on their servers. If there's some kind of limit on what you can do in the game, like which monsters you can attack in your example, it seems like WPE Pro could help there (for instance, if I set a filter on monstername= and make it change the value after that to 31, I will attack the training dummy as long as I attack a monster with a 1 digit identifier). As another idea, it seems that you can be put into negative gold when resurrecting, so maybe if you died a LOT (I assume the price goes up as you get higher leveled), you could get your gold so low that it wraps around to become the highest value it can hold (depends on how they coded it).
I have some stuff to go do, or I'd look at it a little longer. I might try cheatengine on it, or try some of the features besides attacking and buying tomorrow.
