Rinascita Cuirass of Maiming ★★★

Taken all the way down to base materials, one Rinascita Cuirass of Maiming is 2 crafting steps deep and needs 4 intermediates — Ilmenite Ingot ×4, Grade 7 Strength Alkahest ×2, Bayberry Cloth ×1 and 1 other — which resolve to 11 distinct raw materials totalling 45 units, plus 50 crystals.

That bill outweighs 12,451 of the 13,602 recipes tracked here and 1,312 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 44 are burned by the intermediates, so the real crystal cost is 15 Earth Cluster, 12 Fire Cluster, 8 Earth Crystal and 4 other kinds.

The chain crosses five disciplines — Armorer to Lv 90, Alchemist to Lv 90, Blacksmith to Lv 90, Weaver to Lv 90 and Leatherworker to Lv 88 — so no single class can finish it unaided.

6 of the 11 raw materials come out of the ground, and 3 of them are time-gated: Ash Diatomite (10:00, 22:00), Bayberry (4:00, 16:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Ophiotauros Leather has the widest use: 153 recipes call for it, spanning seven of the eight crafting classes.
