Martial Artist's Sleeveless Vest ★★★★

Taken all the way down to base materials, one Martial Artist's Sleeveless Vest is 2 crafting steps deep and needs 2 intermediates — Garnet Cotton ×2 and Softsilver Ingot ×1 — which resolve to 6 distinct raw materials totalling 23 units, plus 24 crystals.

That bill outweighs 8,647 of the 13,602 recipes tracked here and 1,141 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 9 Lightning Cluster, 9 Wind Cluster, 3 Earth Cluster and 1 other kind.

The chain crosses two disciplines — Weaver to Lv 90 and Blacksmith to Lv 90 — so no single class can finish it unaided.

2 of the 6 raw materials come out of the ground, and 2 of them are time-gated: Maghemite (6:00, 18:00) and Softsilver Ore (4:00, 16:00). The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

Of the intermediates, Softsilver Ingot has the widest use: 53 recipes call for it, spanning seven of the eight crafting classes.
