Rinascita Samurai Blade ★★★

Taken all the way down to base materials, one Rinascita Samurai Blade is 2 crafting steps deep and needs 4 intermediates — Ilmenite Ingot ×4, Grade 7 Strength Alkahest ×2, Chondrite Ingot ×1 and 1 other — which resolve to 11 distinct raw materials totalling 46 units, plus 50 crystals.

That bill outweighs 12,540 of the 13,602 recipes tracked here and 1,675 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, 15 Fire Cluster, 8 Fire Crystal and 3 other kinds.

The chain crosses three disciplines — Blacksmith to Lv 90, Alchemist to Lv 90 and Leatherworker to Lv 90 — 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 8 Eorzean hours, about 23 real-world minutes.

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