Bamph

You turn on your heel and vanish in a whirl of dark smoke before reappearing in an unoccupied space you can see within range, leaving a trail of smoke between the two points. During this time, you are resistant to all non-magical damage caused by attacks of opportunity. 

The spell can work through most barriers, as long as line of sight is present, but it is blocked by 1 foot of stone, 1 inch of glass or common metal, a thin sheet of lead, or 3 feet of wood or dirt.
