Cooking Stove ★★★

Taken all the way down to base materials, one Cooking Stove is 2 crafting steps deep and needs 4 intermediates — Darksteel Nugget ×4, Cut Stone ×2, Spruce Lumber ×2 and 1 other — which resolve to 8 distinct raw materials totalling 29 units, plus 30 crystals.

That bill outweighs 10,170 of the 13,602 recipes tracked here and 1,176 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 27 are burned by the intermediates, so the real crystal cost is 12 Fire Crystal, 6 Wind Crystal, 6 Wind Shard and 2 other kinds.

The chain crosses three disciplines — Blacksmith to Lv 50, Carpenter to Lv 50 and Goldsmith to Lv 30 — so no single class can finish it unaided.

5 of the 8 raw materials come out of the ground, and 3 of them are time-gated: Darksteel Ore (1:00), Ferberite (3:00) and 1 other. The widest gap between consecutive opening times is 16 Eorzean hours, about 47 real-world minutes.

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