Milpreves of the Round ★★★

Taken all the way down to base materials, one Milpreves of the Round is 2 crafting steps deep and needs 4 intermediates — Luminous Fiber ×3, Platinum Ingot ×3, Eikon Iron Ingot ×2 and 1 other — which resolve to 13 distinct raw materials totalling 72 units, plus 41 crystals.

That bill outweighs 13,341 of the 13,602 recipes tracked here and 2,160 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 36 are burned by the intermediates, so the real crystal cost is 18 Fire Cluster, 15 Wind Cluster, 4 Earth Cluster and 2 other kinds.

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

7 of the 13 raw materials come out of the ground, and 5 of them are time-gated: Crystallized Sap (8:00, 20:00), Lumythrite Ore (2:00, 14:00) and 3 others. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Platinum Ingot has the widest use: 176 recipes call for it, spanning seven of the eight crafting classes.
