Rakshasa Earring of Aiming ★★★★

Taken all the way down to base materials, one Rakshasa Earring of Aiming is 4 crafting steps deep and needs 7 intermediates — Chigusa Ingot ×1, Evergleam Ingot ×1, Grade 4 Reisui of Dexterity ×1 and 4 others — which resolve to 15 distinct raw materials totalling 36 units, plus 33 crystals.

That bill outweighs 11,383 of the 13,602 recipes tracked here and 1,827 of the 2,216 Goldsmith ones, and 1 recipe nests deeper.

Only 4 of those crystals go into the final step; the other 29 are burned by the intermediates, so the real crystal cost is 9 Fire Crystal, 8 Wind Crystal, 6 Fire Cluster and 4 other kinds.

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

11 of the 15 raw materials come out of the ground, and 3 of them are time-gated: Azim Spring Water (8:00, 20:00), Evergleam Ore (10:00, 22:00) and 1 other. 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.
