Doman Steel-barreled Musketoon

Taken all the way down to base materials, one Doman Steel-barreled Musketoon is 3 crafting steps deep and needs 6 intermediates — Tama-hagane Ingot ×2, Black Firesand ×1, Durium Ingot ×1 and 3 others — which resolve to 10 distinct raw materials totalling 43 units, plus 48 crystals.

That bill outweighs 12,178 of the 13,602 recipes tracked here and 1,542 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 39 are burned by the intermediates, so the real crystal cost is 27 Fire Crystal, 14 Wind Crystal, 4 Earth Crystal and 1 other kind.

The chain crosses four disciplines — Blacksmith to Lv 67, Carpenter to Lv 66, Goldsmith to Lv 66 and Alchemist to Lv 32 — so no single class can finish it unaided.

All 10 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Durium Nugget has the widest use: 142 recipes call for it, spanning seven of the eight crafting classes.
