Everseeker's Needle ★★

Taken all the way down to base materials, one Everseeker's Needle is 2 crafting steps deep and needs 4 intermediates — Sterling Silver Ingot ×3, Alexandrian Plate ×2, Optical Nanofiber ×1 and 1 other — which resolve to 9 distinct raw materials totalling 45 units, plus 50 crystals.

That bill outweighs 12,451 of the 13,602 recipes tracked here and 1,996 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 44 are burned by the intermediates, so the real crystal cost is 12 Fire Cluster, 12 Wind Cluster, 8 Fire Crystal and 4 other kinds.

The chain crosses four disciplines — Goldsmith to Lv 100, Alchemist to Lv 100, Armorer to Lv 100 and Blacksmith to Lv 98 — so no single class can finish it unaided.

5 of the 9 raw materials come out of the ground, and 3 of them are time-gated: Alexandrian Ore (6:00, 18:00), Fine Silver Ore (10:00, 22:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Ra'Kaznar Ingot has the widest use: 166 recipes call for it, spanning seven of the eight crafting classes.
