Bluespirit Cuirass of Fending

Taken all the way down to base materials, one Bluespirit Cuirass of Fending is 2 crafting steps deep and needs 4 intermediates — Bluespirit Tile ×3, Grade 1 Vitality Alkahest ×2, Rose Gold Nugget ×2 and 1 other — which resolve to 9 distinct raw materials totalling 32 units, plus 53 crystals.

That bill outweighs 10,750 of the 13,602 recipes tracked here and 1,133 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 13 of those crystals go into the final step; the other 40 are burned by the intermediates, so the real crystal cost is 21 Fire Crystal, 13 Earth Crystal, 7 Ice Crystal and 2 other kinds.

The chain crosses five disciplines — Armorer to Lv 75, Blacksmith to Lv 74, Leatherworker to Lv 74, Alchemist to Lv 73 and Goldsmith to Lv 50 — so no single class can finish it unaided.

7 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.
