Double Feather Bed ★★

Taken all the way down to base materials, one Double Feather Bed is 3 crafting steps deep and needs 4 intermediates — Vanya Silk ×3, Darksteel Nugget ×2, Mahogany Lumber ×2 and 1 other — which resolve to 7 distinct raw materials totalling 56 units, plus 30 crystals.

That bill outweighs 12,997 of the 13,602 recipes tracked here and 1,920 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 28 are burned by the intermediates, so the real crystal cost is 10 Wind Shard, 9 Lightning Crystal, 6 Fire Crystal and 2 other kinds.

The chain crosses three disciplines — Weaver to Lv 50, Blacksmith to Lv 50 and Carpenter to Lv 39 — so no single class can finish it unaided.

5 of the 7 raw materials come out of the ground, and 3 of them are time-gated: Darksteel Ore (1:00), Silkworm Cocoon (1:00) and 1 other. The widest gap between consecutive opening times is 17 Eorzean hours, about 50 real-world minutes.

Of the intermediates, Silk Thread has the widest use: 175 recipes call for it, spanning six of the eight crafting classes.
