Predecessor Builds > Skylar > 100% Crit Build (Glascannon)

First: If they get you you're gone.

Bloodletter early for more sustain. Can be upraded to Nightfall or sell it for something more useful.
Play safe and don't engage like a braindead monkey. After Imperator is finished make your enemies hate you.
Max out your Q and Ultimate then E.

Works best with a heavy CC support like Riktor or Steel
