As graves, Roaming and picking should be pretty easy for you during this phase of the game. Try to take down unsuspecting enemies in the side lane to make team fights unfair for the enemy.

You will be able to blow up enemies due to your entire build during this phase of the game. Just make sure that you don't get caught out as you are squishy and killed if CC'd during this phase.
