in commonserver there must be the config for land of trial drops (ancient and jog i guess)
castle deep drop items? well then u have to check each monster what it drops between item.txt and mosnter.txt and modify that.
ps: u can't add ancient items Since they are already there just increase the rate etc and change the level of the DROP (eexample 79 or something = hyon/anubis etc)
i already find in CommonServer but there's no Config and icant understandabout Castle deep drop items or maybe ican put index of items/monster/map number Manually in item drop ? Sorry iforgot im using MuEmu S6.3
