Aurum Regis Planisphere

Taken all the way down to base materials, one Aurum Regis Planisphere is 3 crafting steps deep and needs 5 intermediates — Mormorion ×3, Aurum Regis Nugget ×2, Hardsilver Ingot ×2 and 2 others — which resolve to 9 distinct raw materials totalling 51 units, plus 48 crystals.

That bill outweighs 12,830 of the 13,602 recipes tracked here and 2,075 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 45 are burned by the intermediates, so the real crystal cost is 40 Wind Crystal, 5 Water Crystal, 2 Wind Cluster and 1 other kind.

The chain crosses two disciplines — Goldsmith to Lv 60 and Alchemist to Lv 58 — so no single class can finish it unaided.

7 of the 9 raw materials come out of the ground, and one of them is time-gated: Gold Ore (9:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Aurum Regis Nugget has the widest use: 185 recipes call for it, spanning seven of the eight crafting classes.
