Rinascita Culverin ★★★

Taken all the way down to base materials, one Rinascita Culverin is 3 crafting steps deep and needs 5 intermediates — Ilmenite Ingot ×3, Grade 7 Dexterity Alkahest ×2, Titanoboa Leather ×2 and 2 others — which resolve to 11 distinct raw materials totalling 47 units, plus 58 crystals.

That bill outweighs 12,643 of the 13,602 recipes tracked here and 1,700 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 52 are burned by the intermediates, so the real crystal cost is 18 Earth Cluster, 16 Wind Crystal, 12 Fire Cluster and 3 other kinds.

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

Of the intermediates, Star Quartz has the widest use: 157 recipes call for it, spanning seven of the eight crafting classes.
