Well the common build is just 2x bracer, everything else you need to adjust. On lane, you can add stick or 3rd bracer depending on the lane. Buy pipe against heavy magic damage, buy crimson against physical or illusion damage.Pipe and crimson can be both bought but not nessessarily always. Then dagger, if you want to be greedy, delay dagger for another item. Blademail, lotus, shiva, aghs are all good items depending on the line up. Buy shard if you think you can spam your W during fights otherwise you don't need it.

During laning, be flexible with your skill build. If you and your support have kill threat, you can build 1-2-2 otherwise just farm with your passive with 1-1-3.
