High Mythrite Round Knife ★★★

Taken all the way down to base materials, one High Mythrite Round Knife is 3 crafting steps deep and needs 6 intermediates — High Mythrite Ingot ×3, Luminous Fiber ×3, Eikon Leather ×1 and 3 others — which resolve to 17 distinct raw materials totalling 40 units, plus 39 crystals.

That bill outweighs 11,825 of the 13,602 recipes tracked here and 1,447 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 34 are burned by the intermediates, so the real crystal cost is 15 Fire Cluster, 12 Earth Cluster, 4 Lightning Cluster and 2 other kinds.

The chain crosses four disciplines — Blacksmith to Lv 60, Alchemist to Lv 60, Leatherworker to Lv 60 and Goldsmith to Lv 50 — so no single class can finish it unaided.

10 of the 17 raw materials come out of the ground, and 7 of them are time-gated: Crystallized Sap (8:00, 20:00), Lumythrite Ore (2:00, 14:00) and 5 others. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Gold Ingot has the widest use: 184 recipes call for it, spanning seven of the eight crafting classes.
