Adamantite Vambraces of Fending ★★

Taken all the way down to base materials, one Adamantite Vambraces of Fending is 3 crafting steps deep and needs 5 intermediates — Adamantite Ingot ×3, Amphiptere Leather ×1, Aurum Regis Nugget ×1 and 2 others — which resolve to 13 distinct raw materials totalling 36 units, plus 32 crystals.

That bill outweighs 11,383 of the 13,602 recipes tracked here and 1,196 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 28 are burned by the intermediates, so the real crystal cost is 10 Fire Crystal, 5 Earth Crystal, 5 Wind Crystal and 5 other kinds.

The chain crosses five disciplines — Armorer to Lv 60, Alchemist to Lv 60, Blacksmith to Lv 60, Goldsmith to Lv 58 and Leatherworker to Lv 58 — so no single class can finish it unaided.

8 of the 13 raw materials come out of the ground, and 6 of them are time-gated: Adamantite Ore (0:00, 2:00, 6:00, 10:00, 12:00, 14:00, 18:00, 22:00), Blue Quartz (6:00, 18:00) and 4 others. The widest gap between consecutive opening times is 3 Eorzean hours, about 9 real-world minutes.

Of the intermediates, Aurum Regis Nugget has the widest use: 185 recipes call for it, spanning seven of the eight crafting classes.
