Tip for low elo jungle players
I find myself having to tell my jungler this more than I should so I might as well say it here.
A tip for mid -late game. ALWAYS smite your wolves when you take them. Be sure to tell your team not to take the big wolf if they do the camp. This spirit is amazing for vision control.
If your team is playing smart and has upgraded trinkets. Get them to ward the opposite side of the jungle. It lets you get a ton of vision on one side of the map using only normal trinkets. When you get a pink ward always put them on the side of the wolf spirit in the bush. Eventually the spirit will go away and when it does you have great vision on both sides of the jungle without having to stress over anything.
It took me awhile to get my jungler to do so in my recent game but after he did we easily closed the game out because they couldn't do anything outside of their own jungle and even then we had a few wards in theres still. I don't think people understand just how powerful that spirit is.
