a new ability idea. (also my first post)

I have an idea about a new ability. I think it would be fun and interesting for plays: I just imagine a skill-shot similar to Ezreal's Q but it bounces off walls, enemy champions and enemy units. and can maybe keep bouncing off stuff as long as it bounces off enemy unit then a wall then a unit so on and vise versa, so maybe it cant hit another unit until it hits a wall or something.
