Rakshasa Necklace of Fending ★★★★

Taken all the way down to base materials, one Rakshasa Necklace of Fending is 2 crafting steps deep and needs 5 intermediates — Durium Nugget ×1, Grade 4 Reisui of Vitality ×1, Imperial Jade ×1 and 2 others — which resolve to 12 distinct raw materials totalling 26 units, plus 25 crystals.

That bill outweighs 9,543 of the 13,602 recipes tracked here and 976 of the 1,552 Carpenter 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 Wind Crystal, 6 Wind Cluster, 4 Ice Cluster and 3 other kinds.

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

7 of the 12 raw materials come out of the ground, and 3 of them are time-gated: Azim Spring Water (8:00, 20:00), Raw Imperial Jade (6:00, 18:00) and 1 other. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Durium Nugget has the widest use: 142 recipes call for it, spanning seven of the eight crafting classes.
