example....
You learn things as a new character, then when you reach say 30th, the trainer asks you to perform a task (quest) to prove yourself, and if you successfully complete said quest they'll teach you something new..
Theres not much of a difference here to the normal trainer whose skills are just beyond your level except that the skill listing (when you type train) wouldn't show it normally until you finish the quest, but afterwards it would..
I know I know, messy question, my apologies beforehand
