Adamantite Helm of Maiming

Taken all the way down to base materials, one Adamantite Helm of Maiming is 3 crafting steps deep and needs 5 intermediates — Adamantite Nugget ×2, Dragon Leather ×1, Grade 1 Strength Dissolvent ×1 and 2 others — which resolve to 11 distinct raw materials totalling 34 units, plus 38 crystals.

That bill outweighs 11,052 of the 13,602 recipes tracked here and 1,169 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 28 are burned by the intermediates, so the real crystal cost is 19 Fire Crystal, 10 Earth Crystal, 5 Ice Crystal and 1 other kind.

The chain crosses four disciplines — Armorer to Lv 58, Blacksmith to Lv 58, Leatherworker to Lv 56 and Alchemist to Lv 53 — so no single class can finish it unaided.

8 of the 11 raw materials come out of the ground, and 3 of them are time-gated: Adamantite Ore (0:00, 2:00, 6:00, 10:00, 12:00, 14:00, 18:00, 22:00), Darksteel Ore (1:00) and 1 other. The widest gap between consecutive opening times is 4 Eorzean hours, about 12 real-world minutes.

Of the intermediates, Titanium Nugget has the widest use: 112 recipes call for it, spanning six of the eight crafting classes.
