L2 walker and hacks on Private Server

This site offers rewards and stuff for drops of certain mobs, they give away, Video games, RAM, etc.

Is there a way i can find out what creatures drop these special items using walker or some other program?

don't advertise paysites

Im not advertising them, did you even read my post?

I asked if there is a way to find out why to get those books without killing the mob.
