Adamantite Knives

Taken all the way down to base materials, one Adamantite Knives is 3 crafting steps deep and needs 5 intermediates — Adamantite Nugget ×4, Adamantite Rivets ×1, Archaeornis Leather ×1 and 2 others — which resolve to 9 distinct raw materials totalling 41 units, plus 47 crystals.

That bill outweighs 11,923 of the 13,602 recipes tracked here and 1,468 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 37 are burned by the intermediates, so the real crystal cost is 30 Fire Crystal, 8 Earth Crystal, 5 Wind Crystal and 1 other kind.

The chain crosses four disciplines — Blacksmith to Lv 58, Goldsmith to Lv 58, Alchemist to Lv 55 and Leatherworker to Lv 51 — so no single class can finish it unaided.

5 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), Coerthan Tea Leaves (0:00, 8:00, 10:00, 12:00, 20:00, 22:00) 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.
