Adamant Longbow ★★

Taken all the way down to base materials, one Adamant Longbow is 2 crafting steps deep and needs 3 intermediates — Tungsten Steel Ingot ×3, Pliable Glass Fiber ×2 and Lignum Vitae Lumber ×1 — which resolve to 8 distinct raw materials totalling 41 units, plus 31 crystals.

That bill outweighs 11,923 of the 13,602 recipes tracked here and 1,468 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 27 are burned by the intermediates, so the real crystal cost is 8 Earth Cluster, 8 Fire Cluster, 7 Wind Crystal and 2 other kinds.

The chain crosses three disciplines — Blacksmith to Lv 80, Alchemist to Lv 80 and Carpenter to Lv 78 — so no single class can finish it unaided.

3 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Sandalwood Sap (2:00, 14:00) and Tungsten Ore (10:00, 22:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Lignum Vitae Lumber has the widest use: 134 recipes call for it, spanning seven of the eight crafting classes.
