Adamantite Greaves of Fending

Taken all the way down to base materials, one Adamantite Greaves of Fending is 3 crafting steps deep and needs 5 intermediates — Adamantite Nugget ×3, Adamantite Rivets ×1, Chimerical Felt ×1 and 2 others — which resolve to 9 distinct raw materials totalling 33 units, plus 34 crystals.

That bill outweighs 10,907 of the 13,602 recipes tracked here and 1,153 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 31 are burned by the intermediates, so the real crystal cost is 20 Fire Crystal, 5 Lightning Crystal, 4 Water Crystal and 3 other kinds.

The chain crosses four disciplines — Armorer to Lv 60, Blacksmith to Lv 58, Weaver to Lv 58 and Alchemist to Lv 54 — so no single class can finish it unaided.

5 of the 9 raw materials come out of the ground, and 3 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 1 other. The widest gap between consecutive opening times is 4 Eorzean hours, about 12 real-world minutes.

Of the intermediates, Chimerical Felt has the widest use: 113 recipes call for it, spanning six of the eight crafting classes.
