Jeweler's Stall

Taken all the way down to base materials, one Jeweler's Stall is 3 crafting steps deep and needs 11 intermediates — Dwarven Mythril Nugget ×4, Dwarven Cotton ×3, Petalite ×3 and 8 others — which resolve to 12 distinct raw materials totalling 109 units, plus 194 crystals.

That bill outweighs 13,492 of the 13,602 recipes tracked here and 2,182 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 56 of those crystals go into the final step; the other 138 are burned by the intermediates, so the real crystal cost is 119 Wind Crystal, 28 Fire Crystal, 21 Lightning Crystal and 3 other kinds.

The chain crosses four disciplines — Goldsmith to Lv 78, Weaver to Lv 78, Blacksmith to Lv 26 and Carpenter to Lv 26 — so no single class can finish it unaided.

11 of the 12 raw materials come out of the ground, and one of them is time-gated: Raw Petalite (6:00, 18:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Dwarven Cotton has the widest use: 165 recipes call for it, spanning eight of the eight crafting classes.
