As you can tell, this is a bit of an arduous task, and revealing the whole map like this would take a long time. Bees Knees) and Jester Arrows, which can get a little costly and time consuming to make. My secondary method is a regular bow with no additional arrow transforming effects(i.e. With the momentum built up from the grappling hook, the particles emitted from my mount spray in one direction through the wall, revealing it, even though the mount does not spawn when using a grappling hook. My primary method of revealing/lighting up the map is using the Rod of Discord to warp into different parts of caves without the hassle of breaking all of the walls, using my grappling hook, and spamming the Quick Mount button. I have a clemtaminator, which reveals a considerable amount, but still doesn't reveal it SUPER clearly. I have an Ancient Horn, a Spooky Hook, and a Rod of Discord, as well as miscellaneous items to help like the Super Absorbent Sponge. The most recent boss I've defeated was Golem after beating Plantera. I'm around early Hardmode, as you'll see. If you have good items to suggest, let me know, but if you could please refrain from spoiling too much with your responses. I am looking for any items that can shower a lot of particles into walls to light up the map. As stated in the title, I want to reveal the map 'legally', in a manner of speaking. Flying around the map to reveal the skybox is easy enough with some equipment, but revealing the underground sections can be a daunting task. I have figured out a method to do this with, but it's pretty tedious to do. Looking it up online will bring up results of map viewers, but I want to play the game, not cheat my way through. Looking around for a solution for how to erase this fog blocking the map, one will find very scarce resources explaining how to do it. When looking at a map of a Terrarian world, a lot if not most of the map is covered in black as a 'fog', as it were.

Hello, everyone! I have a very specific question, so bear with me here.
