If you are taking the objective build u will obviously go more tankie and take less damaging items. SO you will let your minions do the damage for you. I reccomend you throw your e on them before summoning minions then encase the enemy player with your w and then summon your minions.Then just continue to farm and they will do damage for you. You will want to play passive like that and only go in when the jungler ganks then last hit them with your q.

If you are taking the aggro build then you will take more of the ad items that were listed. I recommend taking this build if you are going up against a melee champ. You will throw your e and encase them with your w and then summon your ult (if you have it) if you dont have your ult just summon your minions. Then you will go in and continue to hit them with your q and auto attacks. That should be easily enough damage to kill them.
