Courtly Lover's Index ★★★★

Taken all the way down to base materials, one Courtly Lover's Index is 2 crafting steps deep and needs 4 intermediates — Fulgurpine Lumber ×3, Double Duraluminum Ingot ×2, Grade 4 Gemsap of Intelligence ×2 and 1 other — which resolve to 12 distinct raw materials totalling 43 units, plus 50 crystals.

That bill outweighs 12,178 of the 13,602 recipes tracked here and 1,489 of the 1,591 Alchemist 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 9 Ice Cluster, 9 Wind Cluster, 8 Water Crystal and 4 other kinds.

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

8 of the 12 raw materials come out of the ground, and 3 of them are time-gated: Dense Aluminum Ore (10:00, 22:00), Fulgurpine Log (8:00, 20:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Double Duraluminum Ingot has the widest use: 40 recipes call for it, spanning five of the eight crafting classes.
