If you wanna watch the combos instead of reading them, here is the same in a video format Play Video
1. Standard Trade
The first combo i wanna show you guys is a pretty standard trading combo.
All you gotta do for this, is to dash forward with your Q, once you are in
W range, press W and knock up the target, Q another time to close the gap or to
dodge an ability from your target and press E. After your E is finished back off!

2. Quick Poke
The second combo can be used to poke the enemy from a safe distance without taking
to much damage. For this, you dash forward with your Q, so you get in E range, press
W to knock up the target and immediatly after, press E. At the time the enemy lands back on the ground you just back off, denying your enemy to react. The good thing about this combo is, its very fast and even if the enemy reacts to that and is able to attack you, the attack wont hurt much, cause your E ability
reduces incoming damage while the ability is channeled.

3. Extended Combo
The third combo is very good in extended fights or teamfights. It allows you to switch easy between targets and you will do the most damage possible in a very short period of time. For this you pull off the standard combo means Q W Q E. But this
time you do not back, instead you autoattack the target twice, dash with your Q, autoattack again twice dash again with Q, autoattack twice, guess what, dash again with Q and autoattack twice. You back off after.

4. Full Combo
The last combo is the full combo. This one can be also used in teamfights or any skirmishes in the jungle. For this you start again with your standard combo Q W Q E followed by two autos into Q, then again two autos into Q, then again two autos into Q. by that time your W is up again, so use it to knock up multiple targets, followed by two autos into Q and finish everything off with another two autos.
