I don't really want to tell you how to play a hero its more for you to find your own play style but I will tell you this spam the **** out of spin webs and spider babies these are crucial for your survival.
----DO NOT GO ANYWHERE WITH OUT WEBS DOWN UNLESS YOU KNOW IT IS SAFE YOU WILL BE GANKED----
If you are owning them will ult spam you so go for a BKB, Heart, and Blade Mail, BM will help you thew most just time it right.
Always check enemy heroes for Dust of Appearance and Gem of True Sight try to get them to waste the dust and the Gem is #1 priority. Let your team know to go for that hero the hardest.
Good Luck and don't **** up
