Chromite Mail of Maiming ★★

Taken all the way down to base materials, one Chromite Mail of Maiming is 3 crafting steps deep and needs 8 intermediates — Chromite Ingot ×3, Gazelle Leather ×2, Grade 2 Reisui of Strength ×2 and 5 others — which resolve to 17 distinct raw materials totalling 73 units, plus 71 crystals.

That bill outweighs 13,354 of the 13,602 recipes tracked here and 1,413 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 67 are burned by the intermediates, so the real crystal cost is 17 Wind Crystal, 15 Fire Crystal, 10 Earth Crystal and 7 other kinds.

The chain crosses five disciplines — Armorer to Lv 70, Alchemist to Lv 70, Blacksmith to Lv 70, Goldsmith to Lv 70 and Leatherworker to Lv 68 — so no single class can finish it unaided.

12 of the 17 raw materials come out of the ground, and 4 of them are time-gated: Chromite Ore (10:00, 22:00), Hallowed Basil (6:00, 18:00) and 2 others. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Palladium Nugget has the widest use: 129 recipes call for it, spanning seven of the eight crafting classes.
