Aatrox fills his Blood Well through his abilities, depleting by (20% maximum) per second while out of combat. When the Blood Well is filled, Aatrox becomes Hellbent for 4 seconds as the Blood Well drains. While Hellbent, dealing or taking damage against enemy champions or neutral monsters will completely fill the Blood Well and refresh Hellbent's duration.
Hellbent:Aatrox gains 25% increased base AD and 30% / 40% / 50% / 60%bonus attack speed. Upon taking fatal damage Aatrox will revive over 3 seconds, recovering 30% of maximum health over the duration. Upon reviving, Aatrox instantly recovers 100% of Blood Well. Aatrox's revive is then put on a cooldown.
Aatrox's resource bar changes to red when Hellbent is active (light red when the revive is off cooldown, dark red when on cooldown)
Aatrox's basic attack animation correlates with the amount of stacks for Blood Thirst/Price. The first basic attack animation (after leveling up Blood Thirst/Price or proccing an empowered basic attack) is Aatrox swinging his sword to the left, the second is to the right and the third basic attack animation (which will be affected by Blood Thirst/Price) is Aatrox stabbing the target.
Blood Thirst/Price will not proc against turrets or wards.
