Courtly Lover's Pistol ★★★★

Taken all the way down to base materials, one Courtly Lover's Pistol is 3 crafting steps deep and needs 5 intermediates — Double Duraluminum Ingot ×3, Grade 4 Gemsap of Dexterity ×2, Rose Garnet ×2 and 2 others — which resolve to 10 distinct raw materials totalling 45 units, plus 58 crystals.

That bill outweighs 12,451 of the 13,602 recipes tracked here and 1,645 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 Fire Cluster, 12 Earth Cluster, 8 Water Crystal and 4 other kinds.

The chain crosses three disciplines — Blacksmith to Lv 100, Alchemist to Lv 100 and Goldsmith to Lv 100 — so no single class can finish it unaided.

7 of the 10 raw materials come out of the ground, and 3 of them are time-gated: Dense Aluminum Ore (10:00, 22:00), Rose Garnet Ore (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, Black Star has the widest use: 161 recipes call for it, spanning six of the eight crafting classes.
