High Durium Planisphere

Taken all the way down to base materials, one High Durium Planisphere is 3 crafting steps deep and needs 6 intermediates — Ametrine ×2, High Durium Nugget ×2, Enchanted Dimythrite Ink ×1 and 3 others — which resolve to 9 distinct raw materials totalling 37 units, plus 84 crystals.

That bill outweighs 11,564 of the 13,602 recipes tracked here and 1,852 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 69 are burned by the intermediates, so the real crystal cost is 54 Wind Crystal, 23 Fire Crystal and 7 Water Crystal.

The chain crosses three disciplines — Goldsmith to Lv 81, Blacksmith to Lv 81 and Alchemist to Lv 78 — so no single class can finish it unaided.

8 of the 9 raw materials come out of the ground, and one of them is time-gated: Raw Onyx (0:00, 12:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, High Durium Nugget has the widest use: 87 recipes call for it, spanning five of the eight crafting classes.
