Black-and-white Interior Wall

Nothing in this list is craftable in turn, so one Black-and-white Interior Wall is a single step: 6 units of material drawn from 3 base items, plus 11 crystals.

That bill outweighs 4,542 of the 13,602 recipes tracked here and 486 of the 1,552 Carpenter ones, and 9,374 recipes nest deeper.

All 3 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Nothing in the data consumes Black-and-white Interior Wall: it is one of 12 end products among the 15 Carpenter recipes at Lv 45.
