Wooden Spiral Staircase

Taken all the way down to base materials, one Wooden Spiral Staircase is 2 crafting steps deep and needs 3 intermediates — Lignum Vitae Lumber ×8, Sandteak Lumber ×7 and Starch Glue ×3 — which resolve to 4 distinct raw materials totalling 72 units, plus 182 crystals.

That bill outweighs 13,341 of the 13,602 recipes tracked here and 1,465 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 56 of those crystals go into the final step; the other 126 are burned by the intermediates, so the real crystal cost is 133 Wind Crystal, 28 Ice Crystal and 21 Water Crystal.

The chain crosses two disciplines — Carpenter to Lv 80 and Alchemist to Lv 75 — so no single class can finish it unaided.

2 of the 4 raw materials match a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.

Of the intermediates, Lignum Vitae Lumber has the widest use: 134 recipes call for it, spanning seven of the eight crafting classes.
