This master yi build is perfectly made for a strong early game DPS plus that this build makes master yi very potent and strong against any opponent

i chose these items for maximum damage and sustainability in lane and against anyone.
after u get the second phantom dancer u should sell the berserker greaves for the 3rd blood thirster.
these items will give u 400 damage and 90% life-steal so u would be able to widstand anything.
when all items are bought sell the boots and buy another phantom dancer
