Rakshasa Mask of Fending ★★★★

Taken all the way down to base materials, one Rakshasa Mask of Fending is 4 crafting steps deep and needs 6 intermediates — Chigusa Ingot ×2, Grade 4 Reisui of Vitality ×1, Palladium Nugget ×1 and 3 others — which resolve to 13 distinct raw materials totalling 31 units, plus 30 crystals.

That bill outweighs 10,578 of the 13,602 recipes tracked here and 1,120 of the 1,441 Armorer ones, and 1 recipe nests deeper.

Only 4 of those crystals go into the final step; the other 26 are burned by the intermediates, so the real crystal cost is 9 Fire Crystal, 5 Wind Crystal, 4 Earth Cluster and 5 other kinds.

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

9 of the 13 raw materials come out of the ground, and 3 of them are time-gated: Azim Spring Water (8:00, 20:00), Gyr Abanian Ore (0:00, 12:00) and 1 other. 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.
