Rinascita Knuckles ★★★

Taken all the way down to base materials, one Rinascita Knuckles is 2 crafting steps deep and needs 4 intermediates — Ilmenite Ingot ×3, Grade 7 Strength Alkahest ×2, Titanoboa Leather ×2 and 1 other — which resolve to 10 distinct raw materials totalling 45 units, plus 50 crystals.

That bill outweighs 12,451 of the 13,602 recipes tracked here and 1,645 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 44 are burned by the intermediates, so the real crystal cost is 18 Earth Cluster, 12 Fire Cluster, 8 Lightning Crystal and 3 other kinds.

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

6 of the 10 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 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, AR-Caean Velvet has the widest use: 136 recipes call for it, spanning six of the eight crafting classes.
