Rinascita Helm of Maiming ★★★

Taken all the way down to base materials, one Rinascita Helm of Maiming is 2 crafting steps deep and needs 4 intermediates — Grade 7 Strength Alkahest ×2, Ilmenite Ingot ×2, Chondrite Ingot ×1 and 1 other — which resolve to 11 distinct raw materials totalling 32 units, plus 38 crystals.

That bill outweighs 10,750 of the 13,602 recipes tracked here and 1,133 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 9 Earth Cluster, 9 Fire Cluster, 8 Fire Crystal and 4 other kinds.

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

7 of the 11 raw materials come out of the ground, and 3 of them are time-gated: Ash Diatomite (10:00, 22:00), Ilmenite (8:00, 20:00) and 1 other. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Chondrite Ingot has the widest use: 210 recipes call for it, spanning seven of the eight crafting classes.
