So I've been a werewolf a long time, and I've never seen a "totem" or anything regarding that, yet all the perks refer to buffing your various "totems"?

I have simple attacks, swipes, and a howl when I use the right bumper that makes enemies flee. So...? Where's the "totems"?

After you beat Companions main quest line. Aela the Huntress will give you quest to get the totems note she will give them at random.

Why is that so obscure? I have literally never heard anything about that, despite completing the companions on 3 different characters.

I guess some figure that they would be taking missions from her for a time. I found this out my first time playing.
