Mythrite Earrings of Gathering

Taken all the way down to base materials, one Mythrite Earrings of Gathering is 2 crafting steps deep and needs 2 intermediates — Mythrite Nugget ×2 and Holy Water ×1 — which resolve to 4 distinct raw materials totalling 16 units, plus 15 crystals.

That bill outweighs 6,959 of the 13,602 recipes tracked here and 1,002 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 9 are burned by the intermediates, so the real crystal cost is 9 Fire Crystal, 3 Water Crystal and 3 Wind Crystal.

The chain crosses three disciplines — Goldsmith to Lv 52, Alchemist to Lv 52 and Blacksmith to Lv 51 — so no single class can finish it unaided.

All 4 raw materials are gathered, and one of them is time-gated: Dravanian Mistletoe (0:00, 12:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Mythrite Nugget has the widest use: 102 recipes call for it, spanning seven of the eight crafting classes.
