Offlane. You have very far night vision, use this to help your allies when they contest the first rune. Your base attack speed is very bad, which will make it difficult to last hit. Once the night at 5 minutes hits, be as aggressive as possible towards enemies in lane. Crippling Fear is a very long silence and Dark Ascension resets it's cooldown, making it even longer potentially. Night Stalker is horrendous at farming so buy a Midas and use it on jungle creeps whenever possible. You can fly over walls and trees during Dark Ascension.
