Adamantite Armor of Fending

Taken all the way down to base materials, one Adamantite Armor of Fending is 4 crafting steps deep and needs 10 intermediates — Adamantite Nugget ×3, Grade 1 Vitality Dissolvent ×2, Darksteel Nugget ×1 and 7 others — which resolve to 12 distinct raw materials totalling 46 units, plus 56 crystals.

That bill outweighs 12,540 of the 13,602 recipes tracked here and 1,324 of the 1,441 Armorer ones, and 1 recipe nests deeper.

Only 10 of those crystals go into the final step; the other 46 are burned by the intermediates, so the real crystal cost is 26 Fire Crystal, 9 Lightning Crystal, 9 Water Crystal and 3 other kinds.

The chain crosses four disciplines — Armorer to Lv 59, Blacksmith to Lv 58, Alchemist to Lv 56 and Weaver to Lv 56 — so no single class can finish it unaided.

10 of the 12 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), Abalathian Mistletoe (6:00, 18:00) and 2 others. The widest gap between consecutive opening times is 4 Eorzean hours, about 12 real-world minutes.

Of the intermediates, Darksteel Nugget has the widest use: 121 recipes call for it, spanning seven of the eight crafting classes.
