there is 2 ways to do this.... but they both contain using variables.
not the easiest things to use if you dont know how to use them fullstop lol. if your going to make it count EVERY mob then can i suggest against the idea lol. it will take along time (as far as i know unless you can encoperate all mobs under one title)
any ways there is a post by preacher tht shows you how to do it through mapquest. other way is to do it in Qfunction using [@onkillmob(mobname)]
also i would read through preachers post n e ways as it shows you how to use variables, which i find easy to use but a pain in the ass to explain lol so i int gunna bother tryin.
hope it helps
peace out
