Figured this would be a great idea but when you shield bash someone with the aetherium shield and they become ethereal then why not use the dragon shout ethereal to change yourself and duel that person on a seperate plane. It would be a great way of killing a specific target if you don't wanna harm someone else in the fight. It would work great against those annoying vampire city attacks provided you hit them and not someone else. Anyone else think this would be cool?

Yes I know almost everyone picked the crown but being able to do this would make you think twice.

But you cant fight or be fought while etheral...

You gotta think though your on the etheral plane with them, so why not be able to battle against that person until the etheral effect ends. Just take away how etheral ends when you attack someone.
