[Autumn]

It currently works against:

Heaven Kick
Jetpack
Rabbit Leap
Basic Movement
Parting shot (somehow)
Crane Hop

Everything else it does not track, basically what you're looking-or rather listening for is the footstep sound while a movement skill is going on, listen closely to jetpack or rabbit leap, you'll hear footstep sounds very faintly.

That indicates the movement skills is built in a way that allows watchful eye to actually watch it.

Anyway I don't think this is a bug? I could be wrong as opinions do change but I brought this up like 2 or 3 years back and these were the only skills specifically changed for watchful eye (Except jetpack, that just happened on its own)
