As you already know, you will have to ask +Colibri to personally make you the taste ID, Item ID, herding and tracking PS's as they don't really exist. BTW - you got a begging and camping 120s? Or did you forget about legendary beggar and camper.
ah did not know ab out taste id, item id, herding, and tracking maybe need to put this on wiki. i take it begging is like camping where you need a ps bag to make it? o.O yeah can't get legendary camper but i'd love the title.
Not sure if begging or camping have 120s either. I have not seen either of them and I do see the PS bag only scrolls sometimes (for example Arms Lore, Poisoning, Disarm). I'm betting that since they are success based skills (ie - skill level = success chance%) there was no need to make them go over 100. Though some success based skills have PSs - hiding for example, but I assume it decreases the minimum range from monsters required to hide (@100 the range is 10 spaces, 120 would most likely make it . Music adds a bonus to associated skills. Arms lore adds a slight bonus to weapons and armor (like 5%DI for weaps or 1% total armor). No idea what would the use* be for 120 in any of the skills you mentioned.
