After Image

You develop an after image trailing behind you at a rapid pace. For the duration, your speed increases by 10 feet and moving doesn't provoke opportunity attacks. 

When you move within 5 feet of a creature, your after image may strike at it. Make a melee spell attack against the target. On a hit, the target takes 1d8 force damage. A creature can be attacked by this spell only once during a turn.

Using a Higher-Level Spell Slot.. Increase your speed by 10 feet for each spell slot level above 2. The after image deals an additional 1d8 force damage for each slot level above 2.
