Titanium Longsword

Taken all the way down to base materials, one Titanium Longsword is 3 crafting steps deep and needs 9 intermediates — Titanium Ingot ×3, Dragon Leather ×1, Hallowed Chestnut Lumber ×1 and 6 others — which resolve to 14 distinct raw materials totalling 63 units, plus 65 crystals.

That bill outweighs 13,204 of the 13,602 recipes tracked here and 1,845 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 56 are burned by the intermediates, so the real crystal cost is 38 Fire Crystal, 9 Earth Crystal, 9 Water Crystal and 1 other kind.

The chain crosses four disciplines — Blacksmith to Lv 57, Alchemist to Lv 56, Carpenter to Lv 56 and Leatherworker to Lv 56 — so no single class can finish it unaided.

10 of the 14 raw materials come out of the ground, and one of them is time-gated: Abalathian Mistletoe (6:00, 18:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Titanium Nugget has the widest use: 112 recipes call for it, spanning six of the eight crafting classes.
