Varrick's Shadow Snap

When you Shadow Snap, you snap between planes. You can see and hear the plane you originated from, but only in shades of grey and you cannot distinguish specific figures. All creatures appear as none descript grey smoke swirls and you cannot tell friend from for. Your vision is limited to 30 ft in every direction. Creatures cannot see you, hear you or sense you, regardless of their abilities. 

For the duration you are snapped, you can move up to 120ft in any direction including vertically or horizontally. You cannot cast spells while snapped but you may attack, move or interact with an object.
