Vanish and Vanishga turn a characters or area of characters (friendly) invisible for a finite period of time. It prevents enemies from detecting you. When you flee, enemies will follow and attempt to attack. It may not be possible to cast the Vanish series without being hit and it canceling. It's a good way to sneak up on enemies, but that's about it. It helps when you are going after bounties.

EDIT: Also. Attacking will cancel the effects of Vanish.
