A little update from watching stream. Rust kushala does not have its own unique theme, that theme is only for the special immortal scar-faced rust kushala in the final village quest. Normal rust kushala can be found in the desert at night with normal kushala theme.

I'll be trying to find vids of it soon, the only new moves(?) I find about it is the new bite attack.
