Use second skill to disrupt enemy's last hit timing, good to push with. Try not to spam too much skill to push, they're excellent skill to dive/gank with. If you have trouble aiming your second skill, you can use your first skill to get close to them before firing second skill. First skill can be stopped by using Super Nova or pressing D or Q again. Dropping Urn, Fire bird, Super Nova can almost always net you a kill.

Carry TP around so you can gank lane that are tower diving, punish them and get gold :)
