Megalodon Jaws ★★

Taken all the way down to base materials, one Megalodon Jaws is 3 crafting steps deep and needs 4 intermediates — Mythril Ingot ×2, Shark Oil ×2, Treated Spruce Lumber ×2 and 1 other — which resolve to 6 distinct raw materials totalling 41 units, plus 34 crystals.

That bill outweighs 11,923 of the 13,602 recipes tracked here and 1,918 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 12 Wind Crystal, 10 Water Shard, 8 Fire Shard and 2 other kinds.

The chain crosses four disciplines — Goldsmith to Lv 50, Carpenter to Lv 50, Alchemist to Lv 41 and Blacksmith to Lv 38 — so no single class can finish it unaided.

5 of the 6 raw materials come out of the ground, and one of them is time-gated: Spruce Log (9:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Mythril Ingot has the widest use: 135 recipes call for it, spanning seven of the eight crafting classes.
