Infernal Archfiend Cloak ★★★

Taken all the way down to base materials, one Infernal Archfiend Cloak is 2 crafting steps deep and needs 2 intermediates — Ilmenite Ingot ×4 and Rutilated Quartz ×2 — which resolve to 5 distinct raw materials totalling 43 units, plus 42 crystals.

That bill outweighs 12,178 of the 13,602 recipes tracked here and 1,542 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 36 are burned by the intermediates, so the real crystal cost is 21 Fire Cluster, 15 Earth Cluster and 6 Wind Cluster.

The chain crosses two disciplines — Blacksmith to Lv 90 and Goldsmith to Lv 90 — so no single class can finish it unaided.

2 of the 5 raw materials come out of the ground, and 2 of them are time-gated: Ilmenite (8:00, 20:00) and Raw Rutilated Quartz (6:00, 18:00). The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

Of the intermediates, Ilmenite Ingot has the widest use: 73 recipes call for it, spanning six of the eight crafting classes.
