Rarefied Mythrite Hauberk

Taken all the way down to base materials, one Rarefied Mythrite Hauberk is 2 crafting steps deep and needs 2 intermediates — Mythrite Nugget ×3 and Archaeornis Leather ×1 — which resolve to 4 distinct raw materials totalling 22 units, plus 18 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 808 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 12 are burned by the intermediates, so the real crystal cost is 9 Fire Crystal, 6 Earth Crystal and 3 Ice Crystal.

The chain crosses three disciplines — Armorer to Lv 52, Blacksmith to Lv 51 and Leatherworker to Lv 51 — so no single class can finish it unaided.

3 of the 4 raw materials come out of the ground, and one of them is time-gated: Coerthan Tea Leaves (0:00, 8:00, 10:00, 12:00, 20:00, 22:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Mythrite Nugget has the widest use: 102 recipes call for it, spanning seven of the eight crafting classes.
