The only way you need to play is to get through laning. Make sure you be aggressive and don't be afraid to engage. As long as the enemy team doesn't get fed, then you'll be near unkillable. Even against a fed team, you will be very hard to take down.

I get boots first, then heartsteel for the perma health stacking, which will boost the damage of the AOE items. Then build unending as your first AOE item, then the rest of your AOE items should be tailored to how much AD or AP the enemy team has

That's literally it. Now simply walk near the enemy and deal ludicrous passive damage that no one can escape, while having ludicrous MR and Armour resist, making u near unkillable. Truly a zzzz build
