I always either prioritize q or max q and e evenly (depending on how I'm doing.) I always get
and
and then from there it's pretty situational. I really enjoy
on him. Then a couple defense items, probably.
As for paths, I usually start a buff and smite it and go right to mid to get a level 2 gank while they're still level 1. I've been thinking about just starting wolves, then going to blue and smiting blue, ganking, then coming back to wolves. But that would leave me low... anyway! There's no real specific paths, because I don't have to worry about the individual smite buffs as much. I try to take the enemy's buffs if I have smite though.
He's an odd champ to play.
