12d6 attack + 8 SPD would be high for me. I would suggest either toning down the STR a bit if the SPD is going to stay high or vice versa.
However this guy’s biggest problem is that he has no movement powers. He seriously needs some extra running and/or leaping. Swimming would be good too. As he is written the player is going to have to use a lot of those 8 actions just getting from point A to B so he has a shot with Totem Man's Hand Attack.
The MP only needs 57 points not 60.
Agree with previous comments about CON, DEX, & INT. Cats, even the big ones, are more well known for DEX than CON. I would raise the INT to 13 or 18 on this guy.
More enhanced senses would also be neat. How about improved hearing or something that lets him sense ‘spirits’ … would be perfect for a supernatural predator.
Skill wise & perk wise he could also use a bit more IMO. KS- Spirit Totems, KS- Native Lore, AK- Home Hunting Grounds, etc. would be perfect add-ons. This guy could also use a contact or two. A shaman that helped him connect with their totem might not be a bad idea.
