Pretty self explanitory, Build health first, then armor or magic resist situationally. I enjoy doing this because you come out of a bush and get a double stun on them, then your ulti if it's needed.

Wraith- Smite The big one, Spam eclipse for the armor
Wolves- Kill em
Blue- Engage it, smite will come up for a perfect timing.
Wraiths again- At this point save smite for the buffs
Golems
Red

Ganking is always viable, just be sure to get your 2 stun's first.
