Dead Man's Chest ★★★

Taken all the way down to base materials, one Dead Man's Chest is 2 crafting steps deep and needs 4 intermediates — Gold Ingot ×2, Ruby ×1, Sapphire ×1 and 1 other — which resolve to 10 distinct raw materials totalling 16 units, plus 18 crystals.

That bill outweighs 6,959 of the 13,602 recipes tracked here and 642 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 15 are burned by the intermediates, so the real crystal cost is 8 Wind Cluster, 4 Fire Cluster, 4 Ice Cluster and 1 other kind.

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

6 of the 10 raw materials come out of the ground, and 5 of them are time-gated: Ferberite (3:00), Gold Ore (9:00) and 3 others. The widest gap between consecutive opening times is 9 Eorzean hours, about 26 real-world minutes.

Of the intermediates, Gold Ingot has the widest use: 184 recipes call for it, spanning seven of the eight crafting classes.
