Rarefied Adamantite Bill

Taken all the way down to base materials, one Rarefied Adamantite Bill is 2 crafting steps deep and needs 3 intermediates — Adamantite Nugget ×2, Amphiptere Leather ×1 and Birch Lumber ×1 — which resolve to 5 distinct raw materials totalling 21 units, plus 31 crystals.

That bill outweighs 8,152 of the 13,602 recipes tracked here and 874 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 20 are burned by the intermediates, so the real crystal cost is 16 Fire Crystal, 10 Earth Crystal and 5 Wind Crystal.

The chain crosses three disciplines — Blacksmith to Lv 60, Carpenter to Lv 58 and Leatherworker to Lv 58 — so no single class can finish it unaided.

4 of the 5 raw materials come out of the ground, and 2 of them are time-gated: Adamantite Ore (0:00, 2:00, 6:00, 10:00, 12:00, 14:00, 18:00, 22:00) and Darksteel Ore (1:00). The widest gap between consecutive opening times is 4 Eorzean hours, about 12 real-world minutes.

Of the intermediates, Amphiptere Leather has the widest use: 108 recipes call for it, spanning seven of the eight crafting classes.
