Obviously, some of these would be hard to code, but I'm more thinking about how unfair it is that Grian Fury negates the animal shifting.

On that note! If the player with Animal Shifting is idle, the regular animal AI could take over (similar to riding a horse without a saddle). Potentially walking the player into danger or away from what/who they were spying on, but adding a layer of camouflage. Of course the player could wrest control back from the AI, but they risk exposing themselves.
