Torch spam everywhere is the bane of many a builder, but in a survival world, it’s seen by most as a necessary evil. Either risk a Creeper attack or shoehorn light sources into a build that might not suit them. What a lot of players don’t realize, though, is that there are a lot of cleaner ways to mob-proof.
A light source placed under the carpet will still light an area up, and the carpet itself is actually a spawn-proof block – as is anything else that doesn’t have a full topside at the conventional height, like a bottom slab or stairs.
