Durium Chaplets

Taken all the way down to base materials, one Durium Chaplets is 3 crafting steps deep and needs 4 intermediates — Azurite ×2, Star Ruby ×2, Durium Nugget ×1 and 1 other — which resolve to 6 distinct raw materials totalling 21 units, plus 40 crystals.

That bill outweighs 8,152 of the 13,602 recipes tracked here and 1,199 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 8 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 26 Wind Crystal, 10 Wind Shard and 4 Fire Crystal.

Every step is Goldsmith work, so one class covers the whole chain.

One intermediate outranks the result: Azurite is a Lv 66 Goldsmith recipe feeding a Lv 65 craft, so that step, not the last one, is the real gate.

All 6 raw materials are gathered, and one of them is time-gated: Raw Azurite (4:00, 16:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.
