Stonegold Syrinxi

Taken all the way down to base materials, one Stonegold Syrinxi is 3 crafting steps deep and needs 4 intermediates — Deepgold Ingot ×2, Stonegold Ingot ×2, Hematite ×1 and 1 other — which resolve to 5 distinct raw materials totalling 29 units, plus 54 crystals.

That bill outweighs 10,170 of the 13,602 recipes tracked here and 1,665 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 42 are burned by the intermediates, so the real crystal cost is 36 Wind Crystal and 18 Fire Crystal.

The chain crosses two disciplines — Goldsmith to Lv 72 and Blacksmith to Lv 72 — so no single class can finish it unaided.

All 5 raw materials are gathered, and 2 of them are time-gated: Raw Hematite (2:00, 14:00) and Gold Ore (9:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Stonegold Ingot has the widest use: 52 recipes call for it, spanning six of the eight crafting classes.
