I recall playing a modpack a few years ago (pretty sure it was in 1.7 if it helps) that had an item in it that looked similar to a botania spark, and when you clicked in midair with it, it shot out of your hand like when you use an ender eye. Then it would go to the center of the chunk you used it in and change the light level of every block in that chunk to 15. I've been looking around for it for a while and I can't seem to find anything like it. I can't remember the name of the item or what mod it came from. Anyone have any idea what that thing might have been?
