Adamantite Trident

Taken all the way down to base materials, one Adamantite Trident is 2 crafting steps deep and needs 4 intermediates — Adamantite Nugget ×3, Amphiptere Leather ×1, Birch Lumber ×1 and 1 other — which resolve to 8 distinct raw materials totalling 34 units, plus 33 crystals.

That bill outweighs 11,052 of the 13,602 recipes tracked here and 1,145 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 30 are burned by the intermediates, so the real crystal cost is 15 Fire Crystal, 5 Earth Crystal, 5 Water Crystal and 3 other kinds.

The chain crosses four disciplines — Carpenter to Lv 60, Alchemist to Lv 59, Blacksmith to Lv 58 and Leatherworker to Lv 58 — so no single class can finish it unaided.

4 of the 8 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.
