About Rolling Cannon Rainbow: Although I haven't seen anything in the data mentioning it, I think Rolling Cannon Rainbow has 3 hitboxes dealing one hit each. This would explain its description, which says it only hits once, and why it hits twice on most mobs I've encountered but only once on snails. The easiest way to confirm this is to go to a mob whose hitbox is bit enough to hit all three lasers (my first thought was PB wizard statues, there might be an easier one somewhere though) and use it without Buckshot on so you can see all lines it hits.
