Silvergrace Needle ★★★

Taken all the way down to base materials, one Silvergrace Needle is 3 crafting steps deep and needs 6 intermediates — Silvergrace Ingot ×6, Hawk's Eye Sand ×3, Ground Sloth Leather ×2 and 3 others — which resolve to 16 distinct raw materials totalling 68 units, plus 50 crystals.

That bill outweighs 13,264 of the 13,602 recipes tracked here and 2,144 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 46 are burned by the intermediates, so the real crystal cost is 15 Wind Cluster, 9 Fire Cluster, 9 Lightning Cluster and 3 other kinds.

The chain crosses four disciplines — Goldsmith to Lv 70, Alchemist to Lv 70, Leatherworker to Lv 70 and Weaver to Lv 60 — so no single class can finish it unaided.

7 of the 16 raw materials come out of the ground, and 5 of them are time-gated: Hawk's Eye (6:00, 18:00), Silvergrace Ore (8:00, 20:00) and 3 others. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Gold Ingot has the widest use: 184 recipes call for it, spanning seven of the eight crafting classes.
