Merchant's Shelf ★

Taken all the way down to base materials, one Merchant's Shelf is 3 crafting steps deep and needs 7 intermediates — Spruce Lumber ×6, Darksteel Plate ×2, Steel Hinge ×2 and 4 others — which resolve to 8 distinct raw materials totalling 47 units, plus 65 crystals.

That bill outweighs 12,643 of the 13,602 recipes tracked here and 1,337 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 60 are burned by the intermediates, so the real crystal cost is 21 Wind Crystal, 16 Water Shard, 12 Fire Crystal and 3 other kinds.

The chain crosses four disciplines — Carpenter to Lv 50, Armorer to Lv 50, Blacksmith to Lv 50 and Alchemist to Lv 41 — so no single class can finish it unaided.

6 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Darksteel Ore (1:00) and Spruce Log (9:00). The widest gap between consecutive opening times is 16 Eorzean hours, about 47 real-world minutes.

Of the intermediates, Steel Ingot has the widest use: 125 recipes call for it, spanning seven of the eight crafting classes.
