Basic attack order is E, a-a, Q, get them in the air and W. The ult is very hard to use. You can use it rarely as a finishing move but most of the time for one v twos and team fights. in a one v two, do the normal stuff, but after you E, ult on your second Q empowered attack and after killing the first one, whip the second one to death. Only do this if they are squishies or if your fed.
In a team fight, what you do is, if theyre carry is in range, E them and ult straight away. If theyre not in range flash to get closer.
Be careful when going in, because apart from flash, you have no escape.

Ganking Lanes
When Ganking Lanes, just do your normal stuff. E, a-a, Q, W. With your laners help it should be easy.

Jungle Clearing. Try and start blue buff. After that take gromp and scuttler. Wolves and Red buff, then try to gank. If not get next scuttler if not taken and gank bot. After that do whatever its not like it affects me.
