Titanium Uchigatana

Taken all the way down to base materials, one Titanium Uchigatana is 4 crafting steps deep and needs 9 intermediates — Titanium Nugget ×3, Electrum Ingot ×1, Holy Cedar Lumber ×1 and 6 others — which resolve to 11 distinct raw materials totalling 46 units, plus 43 crystals.

That bill outweighs 12,540 of the 13,602 recipes tracked here and 1,675 of the 1,932 Blacksmith ones, and 1 recipe nests deeper.

Only 7 of those crystals go into the final step; the other 36 are burned by the intermediates, so the real crystal cost is 16 Fire Crystal, 6 Lightning Crystal, 6 Water Crystal and 4 other kinds.

The chain crosses five disciplines — Blacksmith to Lv 54, Alchemist to Lv 52, Carpenter to Lv 52, Weaver to Lv 52 and Goldsmith to Lv 42 — so no single class can finish it unaided.

9 of the 11 raw materials come out of the ground, 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, Electrum Ingot has the widest use: 234 recipes call for it, spanning seven of the eight crafting classes.
