Totem Warriors are actually possessed by the Animal Spirit.

For slayers it's a primal aspect that is reflective of their spirit guide. As such - there's a small boost to certain attributes, and a couple of abilities such as resistance, 1 level of Increased LP & an Acute Sense.

A better way - may be to go with a generalized aspect of each type of Spirit Guide. In other words have some like the following -

The Panther Aspect - for those with a Jaguar, a Cougar, a Leopard, a Lion or a Tiger spirit guide.

The Canine Aspect - for those with a Wolf, a Coyote, or a wild Dog spirit guide.

The Weasel Aspect - could be for those with a Wolverine, a badger, or a weasel guide.

The Feline Aspect - for those with a wild Cat spirit guide - like a lynx, a Serval, or a Caracal.

The Raptor Aspect - for those with a Bird of Prey (Such as Owl, Falcon, Hawk, or Eagle) spirit guide.
