Atrociraptorskin Armguards of Healing

Taken all the way down to base materials, one Atrociraptorskin Armguards of Healing is 3 crafting steps deep and needs 6 intermediates — Atrociraptor Leather ×2, Grade 1 Mind Alkahest ×1, Iridescent Silk ×1 and 3 others — which resolve to 10 distinct raw materials totalling 27 units, plus 45 crystals.

That bill outweighs 9,763 of the 13,602 recipes tracked here and 1,384 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 13 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 21 Earth Crystal, 9 Lightning Crystal, 9 Wind Crystal and 1 other kind.

The chain crosses four disciplines — Leatherworker to Lv 74, Weaver to Lv 74, Alchemist to Lv 73 and Goldsmith to Lv 50 — so no single class can finish it unaided.

8 of the 10 raw materials come out of the ground, and one of them is time-gated: Gold Ore (9:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Rose Gold Nugget has the widest use: 179 recipes call for it, spanning seven of the eight crafting classes.
