This loop sets up a self-sustaining cycle of devastation by pairing the life-paying finisher of Aetherflux Reservoir with the life-restoring trigger of Exquisite Blood. Once you pay 50 life to activate Aetherflux Reservoir and blast an opponent, that loss of life immediately triggers Exquisite Blood to give you that exact 50 life right back. Because you've recovered the exact amount of life you spent, you can simply repeat the process to blast them again and again until they turn to ash.
