Boltmaster's Needle ★★

Taken all the way down to base materials, one Boltmaster's Needle is 3 crafting steps deep and needs 6 intermediates — Aurum Regis Ingot ×3, Crawler Silk ×2, Astral Birch Lumber ×1 and 3 others — which resolve to 16 distinct raw materials totalling 45 units, plus 35 crystals.

That bill outweighs 12,451 of the 13,602 recipes tracked here and 1,996 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 31 are burned by the intermediates, so the real crystal cost is 15 Wind Crystal, 6 Wind Cluster, 5 Lightning Crystal and 4 other kinds.

The chain crosses four disciplines — Goldsmith to Lv 60, Alchemist to Lv 60, Carpenter to Lv 60 and Weaver to Lv 57 — so no single class can finish it unaided.

10 of the 16 raw materials come out of the ground, and 7 of them are time-gated: Astral Moraine (0:00, 12:00), Aurum Regis Ore (2:00, 14:00) and 5 others. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 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.
