Rinascita Earring of Healing ★★★

Taken all the way down to base materials, one Rinascita Earring of Healing is 2 crafting steps deep and needs 4 intermediates — Chondrite Ingot ×1, Grade 7 Mind Alkahest ×1, Rutilated Quartz ×1 and 1 other — which resolve to 11 distinct raw materials totalling 25 units, plus 32 crystals.

That bill outweighs 9,313 of the 13,602 recipes tracked here and 1,283 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 26 are burned by the intermediates, so the real crystal cost is 9 Wind Cluster, 8 Fire Crystal, 6 Earth Cluster and 3 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 90, Alchemist to Lv 90, Goldsmith to Lv 90 and Blacksmith to Lv 88 — so no single class can finish it unaided.

7 of the 11 raw materials come out of the ground, and 3 of them are time-gated: Ash Diatomite (10:00, 22:00), Haritaki (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, Chondrite Ingot has the widest use: 210 recipes call for it, spanning seven of the eight crafting classes.
