For starters I like this idea, and I think it could add alot and could be fun for a large range of players...but something like this has the potential to be abused quite a bit and I think it needs to be more refined then it currently is. One thing I'm afraid of is the above, yeah it's cool but it could also be construed as quite cringey if not rped properly. Sorry but it's true. I'd suggest turning active glowing eyes into bioluminescent or passive phosphorescent eyes and not making it an ability, it'd make more sense in my opinion but it's up to you.
If I'm being honest, as a player run creature this is pretty op in my opinion. Hearing heartbeats, and smelling creatures from that far away people will get pretty pissed off. You literally couldn't sneak up on them ever, you're not giving players a chance period.
Why gold? Aurum is usually reserved for creatures of the dark.
IDK why this just seems weird, or off in some way. New creatures are supposed to create rp, killing everything as a super wolf doesn't create rp really. Killing people just ends it...explain how this could be fun. For all parties involved. Not only that it goes against the balance you mention a few times through the lore.
So you're telling me these things can cut through steel plate with their teeth and claws?
What? Why?
As a side note I think it'd be a good idea to add some sort of personality influence from this. If you've ever read the wheel of times you know what I'm talking about. Perhaps after several years they have trouble telling the difference between wolf and human forms, and act more aggressive in their human form, perhaps even succumbing to their wolf like nature after a very long time.
As it stands it's a pretty op creature and even as an ET creature it's pretty powerful. It needs to be nerfed a bit if you want to get this accepted in my opinion or people may be upset.
I'd also suggest when it comes to their powers, that in human form it's only slightly enhanced. Also if you do it properly and nerf it down you won't need to be as weak in your human form. Bone diseases? You'll be walking around like a cripple...how's that make for fun rp? Not to mention you note rapid healing during transformation, wouldn't this 'solve' alot of the bone diseases going to and from lycan form?
Sorry if you feel like I'm being too harsh, it's just my opinion. Something like this fits into the fantasy realm of lotc, you just need to get it right. Good luck and feel free to pm me if you want any help or just quote me on the forums!
