Washbasin ★★

Taken all the way down to base materials, one Washbasin is 3 crafting steps deep and needs 6 intermediates — Palladium Ingot ×2, Chromite Ingot ×1, Darksteel Rivets ×1 and 3 others — which resolve to 10 distinct raw materials totalling 39 units, plus 47 crystals.

That bill outweighs 11,756 of the 13,602 recipes tracked here and 1,892 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 33 are burned by the intermediates, so the real crystal cost is 18 Fire Crystal, 17 Wind Crystal, 6 Fire Cluster and 2 other kinds.

The chain crosses two disciplines — Goldsmith to Lv 70 and Blacksmith to Lv 70 — so no single class can finish it unaided.

8 of the 10 raw materials come out of the ground, and 3 of them are time-gated: Chromite Ore (10:00, 22:00), Palladium Ore (4:00, 16:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Palladium Nugget has the widest use: 129 recipes call for it, spanning seven of the eight crafting classes.
