Vanya Hat of Healing ★★

Taken all the way down to base materials, one Vanya Hat of Healing is 4 crafting steps deep and needs 4 intermediates — Rose Gold Nugget ×1, Vanya Silk Hat Lining ×1, Vanya Silk ×1 and 1 other — which resolve to 5 distinct raw materials totalling 22 units, plus 17 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 1,106 of the 1,968 Weaver ones, and 1 recipe nests deeper.

Only 2 of those crystals go into the final step; the other 15 are burned by the intermediates, so the real crystal cost is 9 Lightning Crystal, 3 Lightning Cluster, 3 Wind Crystal and 1 other kind.

The chain crosses two disciplines — Weaver to Lv 50 and Goldsmith to Lv 50 — so no single class can finish it unaided.

4 of the 5 raw materials come out of the ground, and 2 of them are time-gated: Gold Ore (9:00) and Silkworm Cocoon (1:00). The widest gap between consecutive opening times is 16 Eorzean hours, about 47 real-world minutes.

Of the intermediates, Rose Gold Nugget has the widest use: 179 recipes call for it, spanning seven of the eight crafting classes.
