Bad idea of the day #4

I'll try every day to have a "bad idea", And your objective is to try to balance that idea in comments

If you have any stupid idea too, feel free to use riot searching tool to find previous thread to make sure i wasn't stupid previously , i'll be glad to use your idea for a next thread

also i'll always announce who created the most balanced item day n on day n+1 Last best game designer is : no one cuz y'all lazy bois Last day :https://boards.na.leagueoflegends.com/en/c/memes/LaAaJTXa-bad-idea-of-the-day-3

The problem always start with an idea for a part of an item/champion/summoner spell/rune to answer the problem you have to create an entire champion/item/summoner_spell/rune that both contains the gameplay element announced and is balanced. (of course you can comment without participating)

Bad idea of the day #3: Item for ranged champion only that convert the difference between the range at which they are attacking and their max range (sorry but nope rengar) into bonus damage. why is it bad ? Any long range champion would be too strong at close range Now how can we make that any good ? that's the problem for today
