Gemmaster's Trousers ★★

Taken all the way down to base materials, one Gemmaster's Trousers is 3 crafting steps deep and needs 6 intermediates — Astral Silk ×3, Archaeornis Leather ×1, Aurum Regis Ingot ×1 and 3 others — which resolve to 16 distinct raw materials totalling 47 units, plus 33 crystals.

That bill outweighs 12,643 of the 13,602 recipes tracked here and 1,855 of the 1,968 Weaver ones, and 337 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 10 Lightning Crystal, 6 Wind Cluster, 5 Lightning Cluster and 4 other kinds.

The chain crosses four disciplines — Weaver to Lv 60, Alchemist to Lv 60, Goldsmith to Lv 60 and Leatherworker to Lv 51 — so no single class can finish it unaided.

9 of the 16 raw materials come out of the ground, and 7 of them are time-gated: Coerthan Tea Leaves (0:00, 8:00, 10:00, 12:00, 20:00, 22:00), Astral Moraine (0:00, 12:00) and 5 others. The widest gap between consecutive opening times is 4 Eorzean hours, about 12 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.
