Astrolabe ★★

Taken all the way down to base materials, one Astrolabe is 4 crafting steps deep and needs 5 intermediates — Darksteel Nugget ×2, Astrolabe Clinometer ×1, Rose Gold Nugget ×3 and 2 others — which resolve to 5 distinct raw materials totalling 29 units, plus 26 crystals.

That bill outweighs 10,170 of the 13,602 recipes tracked here and 1,665 of the 2,216 Goldsmith ones, and 1 recipe nests deeper.

Only 2 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 15 Wind Crystal, 6 Fire Crystal, 3 Wind Cluster and 1 other kind.

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

4 of the 5 raw materials come out of the ground, and 3 of them are time-gated: Astral Rock (21:00), Darksteel Ore (1:00) and 1 other. The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Rose Gold Nugget has the widest use: 179 recipes call for it, spanning seven of the eight crafting classes.
