Darksteel-barreled Blunderbuss ★★

Taken all the way down to base materials, one Darksteel-barreled Blunderbuss is 3 crafting steps deep and needs 5 intermediates — Black Firesand ×1, Darksteel Ingot ×1, Rose Gold Nugget ×1 and 2 others — which resolve to 9 distinct raw materials totalling 37 units, plus 24 crystals.

That bill outweighs 11,564 of the 13,602 recipes tracked here and 1,403 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 22 are burned by the intermediates, so the real crystal cost is 12 Fire Crystal, 6 Wind Crystal, 3 Water Shard and 2 other kinds.

The chain crosses four disciplines — Blacksmith to Lv 50, Carpenter to Lv 50, Goldsmith to Lv 50 and Alchemist to Lv 32 — so no single class can finish it unaided.

8 of the 9 raw materials come out of the ground, and 3 of them are time-gated: Darksteel Ore (1:00), Gold Ore (9:00) and 1 other. The widest gap between consecutive opening times is 16 Eorzean hours, about 47 real-world minutes.

Of the intermediates, Rose Gold Nugget has the widest use: 179 recipes call for it, spanning seven of the eight crafting classes.
