Can anyone tell me if the first perk is four ranks adding 25% damage each or is it 25% for the first rank and less for the subsequent ranks?

Also, what do the Savage Feeding, Totem of Ice Brothers, and Totem of the Predator perks do? I'm assuming Totem of the Predator is a buff to the detect life howl.

Does anyone know how high the level cap is for the fear howl if you have the Totem of Terror perk?

The very first Perk is +25% per rank leading to +100% damage with a Werewolf's claws once all four ranks are unlocked.

It make Werewolves viable again.

I know because when I only had two of them unlocked, I was killing city guards with one or two swipes.

Thank god I was so worried about that. Thanks.

Can anyone else answer my other questions?

Savage Feeding: Can feed off of any animal and gain health back, not just humanoids.

As far as the Totems go, I never actually tried them out. Another tester (one more werewolf inclined than myself would be helpful. I'm more of a Vampire guy, so I didn't mess around with the Werewolf Perks too much) would be more helpful here as I didn't do the Companion's Radiant Quests enough to even get the Totems much less try them out...

Get totem of the moon, it summons two VERY high level werewolves to help you...

You can tear a whole fort apart with it in a matter of seconds.

It's even better than the fear howl? I always thought that was really useful as long as no one resisted it.

Fear howl was my favorite too.

But I cant resist a pair of werewolves that can take down a dragon on their own

Plus by the time the summon runs out you can just howl again. It recharges very fast.

I wonder if the werewolves you summon are more powerful depending on your level

I'm going to guess yes.

I do not know for sure, but I know not only do they one-shot most types of bandits (which btw they added more bandit types too that are very strong)

But they tank damage for you, as enemies always focus on them. So no more worries about getting kille by stupid arrows if you summon them first.

The health perk makes you pretty tough also.

I only have the first two damage perks and can already tear through everything, power is going to be incredible when maxed out.

Are they just called werewolves or are they named things like Werewolf Brute, Savage, Vargr?

They are named pack member. The wild ones have the names you said.

So what happens after you summoned them? Do they just vanish? How do they even appear? And do they revert to human form?
