Titanium Mask of Aiming

Taken all the way down to base materials, one Titanium Mask of Aiming is 2 crafting steps deep and needs 3 intermediates — Titanium Nugget ×2, Dhalmel Leather ×1 and Rose Gold Nugget ×1 — which resolve to 7 distinct raw materials totalling 22 units, plus 22 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 808 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 15 are burned by the intermediates, so the real crystal cost is 8 Fire Crystal, 7 Earth Crystal, 4 Ice Crystal and 1 other kind.

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

6 of the 7 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.
