Use your slow to get a kill on the rune then go to lane. from time to time you will need to go into the jungle to get gold, but only stay as long as your weak *** cary can hold out. he is your primary concern but if he can handle the lane hes better off with you somewhere else. if need be throw him a heal from time to time, you have Tranquil boots so don't be stingy. mid game you should have your vlads and Maelstrom which will make you a intense pusher. then just throw a seed on the creaps to keep the push at full heath and molly *** the S**t out of those towers. The boots of speed are essential for this because they will allow you to jump from top to bottom pushing out both lanes. If anyone tryes to stop you, use your Scepter on them, turn inadvisable and tp to the other lane.
PS. Tree can use any spell while staying inadvisable
