Scintillant Planisphere ★★★★

Taken all the way down to base materials, one Scintillant Planisphere is 3 crafting steps deep and needs 6 intermediates — Scintillant Ingot ×4, Iolite ×3, Enchanted Platinum Ink ×1 and 3 others — which resolve to 15 distinct raw materials totalling 93 units, plus 72 crystals.

That bill outweighs 13,455 of the 13,602 recipes tracked here and 2,176 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 66 are burned by the intermediates, so the real crystal cost is 33 Fire Cluster, 29 Wind Cluster, 5 Earth Cluster and 2 other kinds.

The chain crosses three disciplines — Goldsmith to Lv 60, Blacksmith to Lv 60 and Alchemist to Lv 50 — so no single class can finish it unaided.

6 of the 15 raw materials come out of the ground, and 5 of them are time-gated: Luminium Ore (6:00, 18:00), Tungstite (2:00, 14:00) and 3 others. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Platinum Ingot has the widest use: 176 recipes call for it, spanning seven of the eight crafting classes.
