Suppose I am a whip spec, and I am a ghost.
I wield a whip, and go to a tough mob wielding a weapon that I want to get.
I strip, and the fight doesn't start. If I manage to catch, I can just walk away.
If I can't catch, the mob doesn't get it from the ground. So I cab just get the weapon and walk away.
This is, sort of, easily abusable.
I'd expect it to start a fight, though I guess it doesn't happen since I do no damage to the mob.
