This item cannot be crafted.

The Blue Slab Wall is a placeable block in the background. Like most walls, it can be used for the housing of NPCs. The Blue Slab Wall cannot be crafted and is instead found only in the Blue Dungeon in worlds created after the 1.2 patch.

It allows Rusty Armored Bones, Ragged Caster, Skeleton Sniper and Giant Cursed Skull to spawn after Plantera has been defeated.
