Cooldown: 225 / 200 / 175 / 150
Upon taking fatal damage, Blood Well activates and places Aatrox in stasis for 3 seconds. Over the stasis duration the Blood Well is emptied and Aatrox restores Health equal to its contents plus 10.5 + (15.75 x level). Blood Well's activation has a static cooldown and is unaffected by cooldown reduction.
Also, Aatrox passively increases his attack speed by 0.6 / 0.7 / 0.8 / 0.9 / 1.0 / 1.1% for every 2% in the Blood Well.
