Blood Well - Abilities League of Legends
When using an ability that costs Health, Aatrox stores the self-inflicted damage into the Blood Well. Upon taking fatal damage, Aatrox extracts the blood from the well and recovers it as Health over a brief duration. Additionally, Aatrox gains 1% Attack Speed for every 2% blood that is in the well.
