Onishi Momohiki ★★★

Taken all the way down to base materials, one Onishi Momohiki is 3 crafting steps deep and needs 7 intermediates — True Linen ×4, Veteran Tree Sap ×3, Silvergrace Ingot ×2 and 4 others — which resolve to 15 distinct raw materials totalling 54 units, plus 37 crystals.

That bill outweighs 12,945 of the 13,602 recipes tracked here and 1,907 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 33 are burned by the intermediates, so the real crystal cost is 12 Lightning Cluster, 8 Wind Cluster, 6 Water Cluster and 4 other kinds.

The chain crosses three disciplines — Weaver to Lv 70, Alchemist to Lv 70 and Goldsmith to Lv 70 — so no single class can finish it unaided.

8 of the 15 raw materials come out of the ground, and 3 of them are time-gated: Hardened Veteran Tree Sap (4:00, 16:00), Hingan Flax (2:00, 14:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Koppranickel Nugget has the widest use: 124 recipes call for it, spanning seven of the eight crafting classes.
