Silvergrace Earrings of Gathering ★★★

Taken all the way down to base materials, one Silvergrace Earrings of Gathering is 3 crafting steps deep and needs 4 intermediates — Silvergrace Ingot ×4, Astral Oil ×2, Hawk's Eye Sand ×1 and 1 other — which resolve to 11 distinct raw materials totalling 35 units, plus 25 crystals.

That bill outweighs 11,223 of the 13,602 recipes tracked here and 1,790 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 21 are burned by the intermediates, so the real crystal cost is 6 Fire Cluster, 6 Wind Cluster, 6 Wind Crystal and 2 other kinds.

The chain crosses two disciplines — Goldsmith to Lv 70 and Alchemist to Lv 70 — so no single class can finish it unaided.

6 of the 11 raw materials come out of the ground, and 4 of them are time-gated: Astral Moraine (0:00, 12:00), Hawk's Eye (6:00, 18:00) and 2 others. The widest gap between consecutive opening times is 4 Eorzean hours, about 12 real-world minutes.

Of the intermediates, Koppranickel Nugget has the widest use: 124 recipes call for it, spanning seven of the eight crafting classes.
