hmm........but it's kinda true.......
casting toughen will gif u 10 hp raise permanently after entering a town, which enables u to cast blood to gold 10 times (if u ahf enough mp...), and that in turn provides u wif a total of 500 gold! not very effective as radek says but when all else fails, u gotta improvise right?
i would do the "use newly created characters as money-makers and take away their gold" method for easy earnings. (each "pool gold" will gif me at least 1000 gold using this method!)
