Titanium Mail of Fending

Taken all the way down to base materials, one Titanium Mail of Fending is 3 crafting steps deep and needs 6 intermediates — Ramie Cloth ×2, Titanium Nugget ×2, Dhalmel Leather ×1 and 3 others — which resolve to 9 distinct raw materials totalling 34 units, plus 33 crystals.

That bill outweighs 11,052 of the 13,602 recipes tracked here and 1,169 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 8 of those crystals go into the final step; the other 25 are burned by the intermediates, so the real crystal cost is 8 Earth Crystal, 8 Fire Crystal, 8 Lightning Crystal and 3 other kinds.

The chain crosses five disciplines — Armorer to Lv 55, Blacksmith to Lv 54, Leatherworker to Lv 54, Weaver to Lv 54 and Goldsmith to Lv 50 — so no single class can finish it unaided.

8 of the 9 raw materials come out of the ground, and one of them is time-gated: Gold Ore (9:00). That window comes round once per Eorzean day, every 70 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.
