Rush GC in the transition into midgame You are strong enough early just with base abilities for ganks and fights Getting it early means a very powerfull spike and you can farm much much faster with it after.
This build focuses on Weapon damage and movement, makes you able to choose your engagements, and flee from anything you know you cant win.
Most of Paradoxes damage in this build comes from her 3 and the burst right after. This makes this build very frontloaded, you dont want prolonged fights. You are essentially an assassin that is pretty useless off cooldown.
Combat barrier and Veilwalker help with survival, but also create another way to assassinate your targets.
