item that passively reduces the amount of lifesteal that damaging you provides. i envision this item on a tankyer build to provide a counter to ppl that you cant kill because they have so much life steal. this item could be limited to the early game by having it remove a fixed amount of health that will end up being less significant in the late game. If it instead was a percentage reduction it could remain relevant later into the game. It could also affect how quickly the mid boss yellow bar refills to help allow for taking it quicker.
