a word of advice try being a bit more specific and polite with your request, alot of work goes into writing scripts and no one is gong to want to make a script for you if thats all you have to say try something like
"Hello, i was wondering if there is currently a script out there or if some one would be willing to write a script that would make different monsters in the battles in different areas of the game map, for instance if you get in a battle in the top right / North east it would only be one type of monster as oposed to a different monster being found exclusively in the south or west, if something like this is possible i would most apreciate it, thank you"
i would doubt there is a scripter on here who would bewilling to do a job on a request like that, your prolly lucky im taking the time to even write this, usualy you would just get a "screw you!, Try please next time -LOCK"
but im nice and not a scriptor so ill give you the benfit of the doubt
