How to Build Walls Underground in Terraria

ReoccuringRace·2 years ago

Building walls underground in Terraria is basically like building above ground but with a couple of twists. First, you gotta clear the area where you want to put your wall. This means mining out any existing blocks in the way. Then, just open your inventory, select the wall type you wanna use (crafted or found), and start placing them by clicking where you want them to go. Remember, walls are for the background, so if you're trying to stop monsters from spawning, this is the way to go!
