Rakshasa Greatshield ★★★★

Taken all the way down to base materials, one Rakshasa Greatshield is 4 crafting steps deep and needs 5 intermediates — Chigusa Ingot ×1, Grade 4 Reisui of Vitality ×1, Palladium Nugget ×1 and 2 others — which resolve to 11 distinct raw materials totalling 25 units, plus 26 crystals.

That bill outweighs 9,313 of the 13,602 recipes tracked here and 922 of the 1,441 Armorer ones, and 1 recipe nests deeper.

Only 4 of those crystals go into the final step; the other 22 are burned by the intermediates, so the real crystal cost is 9 Fire Crystal, 5 Wind Crystal, 4 Earth Cluster and 4 other kinds.

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

8 of the 11 raw materials come out of the ground, and 2 of them are time-gated: Azim Spring Water (8:00, 20:00) and Gyr Abanian Ore (0:00, 12:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Palladium Nugget has the widest use: 129 recipes call for it, spanning seven of the eight crafting classes.
