open the monster.sdata in sh studio, click on a mob, then extend the window that u see the drops, click on a drop back and press CLR and the drop bag is gone out of the mob.
That u have to do with all mobs/bosses.
anyway if u want to do all that stuff read more and use the search function instead of random asking it is already all here in epvpers.
