Start with 2 circlets and get a chicken share with healing. Maybe purchase 1 mana.
ASAP, bottle and ward up, get boots, and complete 2x wb. Don't buy stouts as they are useless unless you're a noob and click-right enemy hero to b.s.
Depending on battle;
Option 1: HotD

Obvious reasons. If you're jungling and get caught by 2 you're ult + b.s. wont save you. Use HotD to get unlimited farming and save your arse
Option 2; PT/2x wb

Adds a lot of chopping power. Good in pub games
Option 3: Farms straight for MKB

If you're a lh/deny machine
Then ofc after MKB and HotD you can farm BoT, keep warding, then farm eagle, get satanic, and finish with a second bfly and then get buriza (at this point, the diminishing returns still adds more dmg than any other wep).
