Rinascita Sword ★★★

Taken all the way down to base materials, one Rinascita Sword is 2 crafting steps deep and needs 3 intermediates — Ilmenite Ingot ×3, Chondrite Ingot ×1 and Grade 7 Vitality Alkahest ×1 — which resolve to 9 distinct raw materials totalling 32 units, plus 38 crystals.

That bill outweighs 10,750 of the 13,602 recipes tracked here and 1,223 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 12 Earth Cluster, 12 Fire Cluster, 8 Fire Crystal and 2 other kinds.

The chain crosses two disciplines — Blacksmith to Lv 90 and Alchemist to Lv 90 — so no single class can finish it unaided.

6 of the 9 raw materials come out of the ground, and 2 of them are time-gated: Ash Diatomite (10:00, 22:00) and Ilmenite (8:00, 20:00). The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

Of the intermediates, Chondrite Ingot has the widest use: 210 recipes call for it, spanning seven of the eight crafting classes.
