i think u have all bot configs right..
so no tricks u need about bot config.
* screen resolution 1024*768
* if u have pet, do not get items from pets bag to your chars bag ( bec. bot can not use those items and even cant see if u have transferred 250 arrows from pets bag )
* if it didnt bought the items u are trying to use ( returnscrolls ) sometimes it cant use them either.
let ur char naked.. stay like 10 mins.. refresh ram , restarting ur computer..
and make bot do everything from the firtspoint..
( its all i have seen during my gameplay. i hate the pet bag thingy.. )
