[Guide] LoL - Aatrox Item Build

Aatrox, the Darkin Blade, is the newest champion in League of Legends. He plays best in top lane due to his high-sustain combined with a lot of melee attack damage. To cast his abilities, Aatrox uses health points instead of mana so no mana items or pots are necessary for him, which makes him an even better top laner.

Heavy Attack Damage Aatrox

You start your lane with a three health pots and a sword which gives you +10 attack damage. This way you can do early damage to your enemy and also lane a very long time due to your pots. Just poke your enemy champion to make him leave the lane so that Aatrox can farm some minions without disturbance.
             When you go back to the shop, go for boots and the Brutalizer. Both makes Aatrox very aggressive. You can chase the enemy much easier and get a kill. The Black Cleaver reduces the enemy's armor, provides you with 200 health, and adds 10% cooldown reduction. The Bloodthirster can be bought even earlier to really just do huge damage without caring about defense. Risky, but sometimes worth it.
This build gives you incredibly high damage output and a little sustain with Warmog's Armor. Aatrox is a bruiser, meaning he combines damage with health like Kha'Zix, Darius, or Jax.

Hard Lane / More Defense Build

If you're facing a really hard champion like a fed Jax for example, you should prefer this build. The same when your jungler failed to gank your lane but the enemy jungler has already killed you a couple of times.
The early hextrinker gives you magic resist and a shield which can often save your life. Followed by Mercury's Treads and Warmog's gives the enemy champ no chance to kill you because of your high-sustain. Against heavy AD like Darius you should buy Randiun's Omen.
This build gives you more defense like the one above but you do less damage, of course. This way, your whole team is more tanky, maybe giving you the advantage to win the map. Especially when you don't have other tanks, you shouldn't go for pure damage output.

As said above, Aatrox needs defensive and offensive runes as well. This way you are prepared for everything that could happen on your lane or in later teamfights.
