Platinum Planisphere ★★★★

Taken all the way down to base materials, one Platinum Planisphere is 2 crafting steps deep and needs 4 intermediates — Platinum Ingot ×3, Wootz Ingot ×2, Enchanted Platinum Ink ×1 and 1 other — which resolve to 10 distinct raw materials totalling 48 units, plus 33 crystals.

That bill outweighs 12,691 of the 13,602 recipes tracked here and 2,043 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 29 are burned by the intermediates, so the real crystal cost is 12 Fire Cluster, 10 Wind Cluster, 6 Earth Cluster and 2 other kinds.

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

1 of the 10 raw materials come out of the ground, and one of them is time-gated: Platinum Ore (4:00). That window comes round once per Eorzean day, every 70 real-world minutes.

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