Imperial Jade Necklace of Fending

Taken all the way down to base materials, one Imperial Jade Necklace of Fending is 2 crafting steps deep and needs 3 intermediates — Imperial Jade ×2, Grade 1 Reisui of Vitality ×1 and Twinthread ×1 — which resolve to 9 distinct raw materials totalling 20 units, plus 27 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 1,141 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 16 Wind Crystal, 5 Fire Crystal, 4 Water Crystal and 1 other kind.

The chain crosses three disciplines — Goldsmith to Lv 70, Weaver to Lv 68 and Alchemist to Lv 63 — so no single class can finish it unaided.

All 9 raw materials are gathered, and 2 of them are time-gated: Raw Imperial Jade (6:00, 18:00) and Almandine (0:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Twinthread has the widest use: 109 recipes call for it, spanning six of the eight crafting classes.
