WildHunters jaguar + MapleStory cash effects?

I have a question about the cash shop effects like for example Return of the angel wing. (I really want it @_@)
If it works well when you're on a jaguar D:

Well i know it will show but will it like something dissapear in certain poses the char makes?
I don't really know how to explain this actually...

Well..
Would the effect have any interfalls? or invisible frames with some attacks or moves?

Would appreciate any info

Thanks in advance
