Early game you focus on using your Q to poke the enemy and heal your adc. If you reach level 2 before the enemy bot lane, you can surprise them with a W, Q, depending on how low you and your adc is for a decent trade.

Early to Mid game focus on keeping your adc alive with healing and shielding and looking for good engages with your W and R. Ward river and tri bush to keep the 2v2 from becoming q 3v2 or a 4v2.

Mid game is kinda a cluster**** at times. Keep poking with Q and looking for good picks with W. If the fight is going south, E to low allies and **** off.

Late game just stick with adc and whoever is carrying to help catch out squishies or start advantageous team fights, keep warding objectives and blind spots.
