Diabolos Miniature ★★★

Taken all the way down to base materials, one Diabolos Miniature is 3 crafting steps deep and needs 3 intermediates — High Mythrite Ingot ×3, Eikon Leather ×2 and Camphor ×6 — which resolve to 7 distinct raw materials totalling 38 units, plus 38 crystals.

That bill outweighs 11,698 of the 13,602 recipes tracked here and 1,875 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 33 are burned by the intermediates, so the real crystal cost is 12 Earth Cluster, 11 Fire Cluster, 7 Wind Cluster and 2 other kinds.

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

4 of the 7 raw materials come out of the ground, and 2 of them are time-gated: Lumythrite Ore (2:00, 14:00) and Wattle Bark (2:00, 14:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, High Mythrite Ingot has the widest use: 150 recipes call for it, spanning seven of the eight crafting classes.
