skill questions

im starting this thread to get information on aquiring skills. i have a lvl 15 necro/ranger and ive gone to many places that are supposed to have certain skills for both yet only find ranger skills or necro only. for ex: the ice tooth cave skill trainer is supposed to have about 6 skills for each class but when i go to him hes only got about 3 ranger skills. can someone tell me whats up? by doing so im sure youll answer this question for others as well. anyway good questing everyone and dont forget to give me all your gold items you find

Skill trainers will only list the skills they possess which you DO NOT ALREADY know. So if he is showing no necro skills, it is because of the ones he knows, you already have.
