ok ive beaten the game with all parties and combos possiable. both dos and psx and wsc and nes verisons.
to answewr your qs its yes to both
it may take some time but you can do it and it will prove much easier if you want to wast time. since you can find items in the game to permenently raise stats just keep getting them and eventually tou will get there. or just do it the old fashind way max level and practice and luck. either way you can do it. unless you still think 4 monks is a good idea. its not.well not entirely but dont wory youll do fine
