Meteorite Brick

Raw Meteorite sets you on fire the moment you touch it, which makes building with the stuff miserable unless you are burning through Obsidian Skin Potions. The brick keeps the look and drops the burn entirely, so this is what you actually place when you want a meteorite room rather than a hazard.

It gives off a faint glow on its own. Not enough to light a room properly, but enough that a wall of it stops reading as pitch black, which is handy for corridors where you do not want visible torches. Explosives still tear through it, so do not treat a meteorite wall as protection.
