Classical Gunblade ★★

Taken all the way down to base materials, one Classical Gunblade is 2 crafting steps deep and needs 4 intermediates — Lunar Adamantite Ingot ×3, Grade 6 Vitality Alkahest ×2, Rhodium Ingot ×2 and 1 other — which resolve to 11 distinct raw materials totalling 41 units, plus 50 crystals.

That bill outweighs 11,923 of the 13,602 recipes tracked here and 1,468 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 Fire Cluster, 12 Earth Cluster, 8 Fire Crystal and 3 other kinds.

The chain crosses three disciplines — Blacksmith to Lv 90, Alchemist to Lv 90 and Goldsmith 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: Double-edged Herb (10:00, 22:00), Lunar Adamantite Ore (2:00, 14:00) 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.
