Alkalurops ★★

Taken all the way down to base materials, one Alkalurops is 4 crafting steps deep and needs 6 intermediates — Spruce Lumber ×2, Darksteel Nugget ×1, Suspended Trillium Flower ×1 and 3 others — which resolve to 7 distinct raw materials totalling 27 units, plus 19 crystals.

That bill outweighs 9,763 of the 13,602 recipes tracked here and 1,338 of the 1,591 Alchemist ones, and 1 recipe nests deeper.

Only 2 of those crystals go into the final step; the other 17 are burned by the intermediates, so the real crystal cost is 6 Wind Crystal, 3 Fire Crystal, 3 Water Cluster and 3 other kinds.

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

6 of the 7 raw materials come out of the ground, and 4 of them are time-gated: Darksteel Ore (1:00), Spruce Log (9:00) and 2 others. The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Darksteel Nugget has the widest use: 121 recipes call for it, spanning seven of the eight crafting classes.
