Oriental Wood Bridge ★★★

Taken all the way down to base materials, one Oriental Wood Bridge is 3 crafting steps deep and needs 6 intermediates — Ancient Lumber ×8, Cobalt Nails ×8, Treated Camphorwood Lumber ×6 and 3 others — which resolve to 12 distinct raw materials totalling 120 units, plus 187 crystals.

That bill outweighs 13,498 of the 13,602 recipes tracked here and 1,518 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 182 are burned by the intermediates, so the real crystal cost is 80 Fire Shard, 48 Water Shard, 37 Wind Cluster and 1 other kind.

The chain crosses three disciplines — Carpenter to Lv 60, Blacksmith to Lv 44 and Alchemist to Lv 41 — so no single class can finish it unaided.

7 of the 12 raw materials come out of the ground, and 2 of them are time-gated: Old-growth Camphorwood Log (8:00, 20:00) and Scarlet Sap (3:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Cobalt Ingot has the widest use: 145 recipes call for it, spanning seven of the eight crafting classes.
