Aatrox, the Darkin Blade is the most recently released champion in League of Legends. He is classified as a melee fighter but can also be quite tanky due to his passive and built-in life regeneration abilities. Aatrox is hard to kill and when his passive is up, you will have to kill him twice.
His passive is called Blood Well. Whenever he uses an ability that costs health, he stores that health lost into the blood well. Once Aatrox dies, he will automatically come back to life with hit points equal to the contents of the well plus a certain amount extra based on his level. The maximum amount of total health he can store increases as he levels up. Blood Well is also useful while Aatrox is alive since it increases his attack speed by 1% for every 2% in the well.
Aatrox’s ‘Q’ is Dark Flight. He jumps into the air and then slams the ground a short distance away, dealing physical damage and knocking enemies into the air for one second in an area of effect. This ability makes Aatrox a pretty good ganker since he can fly out of the bushes and onto opponents. It can also be used to initiate battles or to aid in his escape if need be. Each Dark Flight costs 10% of his current HP though, so don’t overuse it needlessly.
His ‘W’ is actually two passive abilities that can be toggled between one another. When Aatrox has Blood Thirst activated, he will heal himself on every third basic attack. The amount healed scales with his attack damage at the rate of 25%. That might not seem like all that much but if Aatrox has below half health, the heal scales to a bonus based off 75% of his AD. This can make him very hard to kill as long as he keeps attacking. Most players have an instinct to flee from a battle as their hit points begin to get low, but Aatrox players should stay. This heal will help Aatrox win many one on one duels, especially if you have built items that also have life steal.
The other half of his ‘W’ is called Blood Price. It works in the same way as Blood Thirst, but rather than healing you every third attack, it deals significant bonus physical damage. When maxed out, Blood Price will deal 200 base damage +100% bonus AD. You can imagine how powerful this would become late game. The only drawback is that it also costs you health on each third attack, so you can’t just keep Blood Price on the whole game. You must be smart and have Blood Price activated when your health is near full and switch to Blood Thirst when your health falls below half in order to heal yourself back up.
