High Mythrite File ★★★

Taken all the way down to base materials, one High Mythrite File is 3 crafting steps deep and needs 6 intermediates — Luminous Fiber ×3, High Mythrite Ingot ×2, Eikon Leather ×1 and 3 others — which resolve to 17 distinct raw materials totalling 33 units, plus 34 crystals.

That bill outweighs 10,907 of the 13,602 recipes tracked here and 1,266 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 29 are burned by the intermediates, so the real crystal cost is 12 Fire Cluster, 10 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.
