Double-jointed Adamantite Pliers ★★

Taken all the way down to base materials, one Double-jointed Adamantite Pliers is 3 crafting steps deep and needs 4 intermediates — Adamantite Ingot ×3, Adamantite Rivets ×1, Shark Oil ×1 and 1 other — which resolve to 9 distinct raw materials totalling 32 units, plus 33 crystals.

That bill outweighs 10,750 of the 13,602 recipes tracked here and 1,223 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 29 are burned by the intermediates, so the real crystal cost is 20 Fire Crystal, 5 Water Shard, 4 Earth Cluster and 1 other kind.

The chain crosses two disciplines — Blacksmith to Lv 60 and Alchemist to Lv 41 — so no single class can finish it unaided.

6 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), Blue Quartz (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, Adamantite Nugget has the widest use: 79 recipes call for it, spanning six of the eight crafting classes.
