You CAN tame wolves and have them follow you.. but that has nothing to do with magic or this update at all and there is no "skill" tied to it. There is a YT video of a player strictly using wolves to beat the first 5 bosses.

Hunter skills would just be like your bow and weapon skill.. no "hunter" skill. Also by skill are you meaning like an skill you level up or an ability you have an action you can do?
