Courtly Lover's Baghnakhs ★★★★

Taken all the way down to base materials, one Courtly Lover's Baghnakhs is 2 crafting steps deep and needs 4 intermediates — Double Duraluminum Ingot ×4, Grade 4 Gemsap of Strength ×2, Gargantua Leather ×1 and 1 other — which resolve to 10 distinct raw materials totalling 43 units, plus 50 crystals.

That bill outweighs 12,178 of the 13,602 recipes tracked here and 1,542 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, 15 Earth Cluster, 8 Earth Crystal and 3 other kinds.

The chain crosses four disciplines — Blacksmith to Lv 100, Alchemist to Lv 100, Goldsmith to Lv 100 and Leatherworker to Lv 98 — so no single class can finish it unaided.

6 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, Gargantua Leather has the widest use: 89 recipes call for it, spanning five of the eight crafting classes.
