Mythrite-barreled Musketoon

Taken all the way down to base materials, one Mythrite-barreled Musketoon is 3 crafting steps deep and needs 7 intermediates — Mythrite Ingot ×2, Black Firesand ×1, Holy Cedar Lumber ×1 and 4 others — which resolve to 10 distinct raw materials totalling 50 units, plus 40 crystals.

That bill outweighs 12,777 of the 13,602 recipes tracked here and 1,723 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 33 are burned by the intermediates, so the real crystal cost is 22 Fire Crystal, 9 Wind Crystal, 3 Earth Crystal and 2 other kinds.

The chain crosses three disciplines — Blacksmith to Lv 53, Alchemist to Lv 52 and Carpenter to Lv 52 — so no single class can finish it unaided.

All 10 raw materials are gathered, and one of them is time-gated: Dravanian Mistletoe (0:00, 12:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Mythrite Nugget has the widest use: 102 recipes call for it, spanning seven of the eight crafting classes.
