Although this is not meant to be an in-depth build guide, players should keep in mind
Aatrox is best built as a tanky bruiser so you should buy items that will boost both
his attack and defense in some small way. For boots, focus on defense and pick up
Ninja Tabi or Mercury Treads depending on the composition of the enemy team. Attack
speed is important for Aatrox to hit his third attacks from Blood Thirst / Blood
Price more often. Blade of the Ruined King is essential for its attack speed bonus
and added life steal which both keep him alive in prolonged engagements.
Bloodthirster (or Sanguine Blade on Dominion) is another item that Aatrox should
definitely get for the lifesteal bonuses. Spirit Visage is another essential since it
increases his self-healing by 20%.
Depending on how you need to play him here are some other items to consider:
Zephyr has a lot of perks but the attack speed bonus is especially valuable to
Aatrox. If you don’t have Merc Treads and need tenacity, buy this.
Maw of Malmortius is good against teams heavy on AP
Sunfire Cape is useful for teams with heavy physical damage
Frozen Mallet for the increased hit points and
