Wootz Mask ★★★★

Taken all the way down to base materials, one Wootz Mask is 2 crafting steps deep and needs 4 intermediates — Wootz Ingot ×3, Darksteel Nugget ×1, Platinum Nugget ×1 and 1 other — which resolve to 7 distinct raw materials totalling 15 units, plus 25 crystals.

That bill outweighs 6,735 of the 13,602 recipes tracked here and 616 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 21 are burned by the intermediates, so the real crystal cost is 9 Earth Cluster, 9 Fire Cluster, 3 Fire Crystal and 2 other kinds.

The chain crosses three disciplines — Armorer to Lv 50, Blacksmith to Lv 50 and Goldsmith to Lv 50 — so no single class can finish it unaided.

4 of the 7 raw materials come out of the ground, and 3 of them are time-gated: Darksteel Ore (1:00), Ferberite (3:00) and 1 other. The widest gap between consecutive opening times is 21 Eorzean hours, about 61 real-world minutes.

Of the intermediates, Darksteel Nugget has the widest use: 121 recipes call for it, spanning seven of the eight crafting classes.
