Titanium Mask of Fending

Taken all the way down to base materials, one Titanium Mask of Fending is 3 crafting steps deep and needs 3 intermediates — Titanium Nugget ×3, Rose Gold Nugget ×1 and Titanium Rivets ×1 — which resolve to 5 distinct raw materials totalling 25 units, plus 26 crystals.

That bill outweighs 9,313 of the 13,602 recipes tracked here and 922 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 19 are burned by the intermediates, so the real crystal cost is 16 Fire Crystal, 4 Ice Crystal, 3 Earth Crystal and 1 other kind.

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

All 5 raw materials are gathered, 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.
