I'll be quick.

In the beginning, the boots of speed are exactly what you need, supported by three health pots. Mid is for you . You can easily place your Mystic shot and harass endlessly thanks to your mobility.

Back whenever you can take Wriggle's Lantern, or at least Madred's razor. Then you need Sheen. Your burst is getting amazing. Moreover, Wriggle's Lantern is probably one of the best carry item, helping a lot your survival. Plus try to always keep three Health pots on you until level 11.
Runes of Mana regeneration helps you keep the mid safe in early game. Mana during middle game is not an issue since you're getting blue quite easily thanks to the lantern.

Now get trinity : you need the 150 %, the slow, the mobility, and the attack speed. Incredible item.
Keep harassing, try to keep you're Arcane shift, unless you're doing 3-1-2-1 combo. You're hot in early game, cute in mid... A god in the end.
Remember to place Essence flux on your carries... A good carry is better than a few damage.

Madred's Bloodrazor signs the end of their assurance. Call me the Death Whisperer !
If the party goes on, You can switch your lantern with Bloodthirster for extra damage, although you don't need it. Same thing for Hexdrinker and Banshee's Veil.

SKILL REQUIRED. Enjoy. OS the map.
