Hardsilver Earrings of Gathering

Taken all the way down to base materials, one Hardsilver Earrings of Gathering is 3 crafting steps deep and needs 3 intermediates — Hardsilver Ingot ×2, Hallowed Water ×1 and Hardsilver Nugget ×2 — which resolve to 5 distinct raw materials totalling 24 units, plus 32 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 1,346 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 23 are burned by the intermediates, so the real crystal cost is 23 Wind Crystal, 5 Water Crystal and 4 Fire Crystal.

The chain crosses two disciplines — Goldsmith to Lv 57 and Alchemist to Lv 56 — so no single class can finish it unaided.

All 5 raw materials are gathered, and one of them is time-gated: Abalathian Mistletoe (6:00, 18:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Hardsilver Ingot has the widest use: 117 recipes call for it, spanning seven of the eight crafting classes.
