Aatrox, the Darkin Blade is a melee fighterchampion whose versatile abilities specialize in strong initiation and self-sustain. Possessing exceptional attack speed and durability from his passive, Aatrox excels as a duelist and initiator, leaping onto single opponents or entire teams, recovering from injury just by trading blows, applying pressure from afar, and can even briefly empower himself to aggressively pursue fleeing foes.
Aatrox's secondary resource bar displays his Blood Well. Whenever Aatrox uses an ability that costs health, he stores 100% of the self-inflicted damage into his Blood Well, which can hold up to 105 / 138 / 171 / 207 / 244 / 283 / 323 / 365 / 408 / 453 / 500 / 548 / 598 / 649 / 702 / 756 / 813 / 870 health. If Aatrox has not dealt nor received damage in the last 5 seconds, his Blood Well will deplete at a rate of 2% per second.
STATIC COOLDOWN: 225
Aatrox's attack speed is increased by 0.6 / 0.7 / 0.8 / 0.9 / 1 / 1.1% for every 2% in his Blood Well, up to a maximum of 30 / 35 / 40 / 45 / 50 / 55% bonus attack speed.
Upon taking fatal damage, Aatrox enters a stasis and begins draining his Blood Well, healing himself over the next 3 seconds. The amount of health restored is equal to 35% of the Blood Well's content limit, plus its amount of stored health upon activation. After 1 second, Aatrox can end the stasis early by moving, which also ends the health restoration.
Blood Well is both a self-targeted buff and a passive ability that triggers when Aatrox takes fatal damage.
The maximum health Blood Well can restore is 141.75 / 186.3 / 230.85 / 279.45 / 329.4 / 382.05 / 436.05 / 492.75 / 550.8 / 611.55 / 675 / 739.8 / 807.3 / 876.15 / 947.7 / 1020.6 / 1097.55 / 1174.5
This is equivalent to 135% of the Blood Well's content, but the heal is composed of a base value of 35% of the maximum pool, plus 1% per 1% of its current content.
