Adamantite Leg Guards of Maiming

Taken all the way down to base materials, one Adamantite Leg Guards of Maiming is 2 crafting steps deep and needs 4 intermediates — Adamantite Nugget ×2, Amphiptere Leather ×1, Aurum Regis Nugget ×1 and 1 other — which resolve to 9 distinct raw materials totalling 29 units, plus 27 crystals.

That bill outweighs 10,170 of the 13,602 recipes tracked here and 1,028 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 10 Fire Crystal, 5 Earth Crystal, 5 Wind Crystal and 3 other kinds.

The chain crosses five disciplines — Armorer to Lv 60, Blacksmith to Lv 58, Goldsmith to Lv 58, Leatherworker to Lv 58 and Alchemist to Lv 53 — so no single class can finish it unaided.

6 of the 9 raw materials come out of the ground, and 4 of them are time-gated: Adamantite Ore (0:00, 2:00, 6:00, 10:00, 12:00, 14:00, 18:00, 22:00), Darksteel Ore (1:00) and 2 others. The widest gap between consecutive opening times is 4 Eorzean hours, about 12 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.
