Gold Brick Wall

Two things set this apart from most walls you find underground. It counts as safe, so enemies will not spawn against it, and it can be crafted, so you never have to strip a shrine bare to get more of it.

That combination makes a Jungle Shrine an unusually good place to set up. Most natural structures need their walls torn out and replaced before the room is livable. This one you can move into as it stands. If you are laying out a jungle outpost or a farm floor, running the same brick across the whole area keeps the spawn suppression consistent without breaking the look.
