Ala Mhigan Round Knife ★★

Taken all the way down to base materials, one Ala Mhigan Round Knife is 3 crafting steps deep and needs 5 intermediates — Snailfish Oil ×3, Chromite Ingot ×1, Gazelle Leather ×1 and 2 others — which resolve to 13 distinct raw materials totalling 39 units, plus 35 crystals.

That bill outweighs 11,756 of the 13,602 recipes tracked here and 1,437 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 31 are burned by the intermediates, so the real crystal cost is 6 Lightning Cluster, 6 Water Cluster, 5 Earth Crystal and 4 other kinds.

The chain crosses three disciplines — Blacksmith to Lv 70, Alchemist to Lv 70 and Leatherworker to Lv 68 — so no single class can finish it unaided.

5 of the 13 raw materials come out of the ground, and one of them is time-gated: Chromite Ore (10:00, 22:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Chromite Ingot has the widest use: 121 recipes call for it, spanning six of the eight crafting classes.
