Adamantite Saw

Taken all the way down to base materials, one Adamantite Saw is 3 crafting steps deep and needs 3 intermediates — Adamantite Nugget ×4, Adamantite Rivets ×1 and Birch Lumber ×1 — which resolve to 3 distinct raw materials totalling 29 units, plus 33 crystals.

That bill outweighs 10,170 of the 13,602 recipes tracked here and 1,176 of the 1,932 Blacksmith ones, and 337 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 25 Fire Crystal, 5 Wind Crystal, 2 Fire Cluster and 1 other kind.

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

All 3 raw materials are gathered, 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, Adamantite Nugget has the widest use: 79 recipes call for it, spanning six of the eight crafting classes.
