An idea for an Aatrox buff
When Aatrox's passive is popped while his ultimate is active, he will regenerate health as normal, but he will additionally slow and drain the health of enemy champions around him, dealing magic damage proportionate to their maximum health, healing himself after reductions. Percent magic damage scales with Aatrox's level.
This healing is increased by Spirit Visage, but not the damage. This damage cannot kill. It will leave opponents at 1 health if they reach it, but Aatrox will continue healing from them as if they had more health.
To stop being drained, enemy champions can simply walk out of the aoe.
