My farming Teemo,
Start items:
Refillable pot+Faerie Charm+Faerie Charm+vision ward+Blind+teleport+heal
Even if toplane, you run to botlane river at game starts.
If nxt drake is cloud drake, i put vision ward upthere at the 1.10mark, if not i put it at allied toplane red buff
If used vision ward on cloud, i use trinket on allied topside buff
If jgler starts at toplane allied buff, and there is no cloud, i put vision ward at allied botlane buff
At lvl6-8, at the cost of leading lane, even if not have Liandry, you still shroom the drakeside and botlane river
