So i have tried Various item builds with Lucian and this one works extremely well Lucian is a very slow toon so you will need to look it to his attack speed and movement speed to help bring him up to par like other ADC's like MF Caitlyn and ashe. a strong start can help win the lane early on I highly recommend a doran's blade as it helps u stay in lane longer allowing you to make as much cash as possible early game. this build is comprised of attack speed life steal and crits make good use of it :D
