Courtly Lover's Codex ★★★★

Taken all the way down to base materials, one Courtly Lover's Codex is 2 crafting steps deep and needs 4 intermediates — Fulgurpine Lumber ×3, Grade 4 Gemsap of Mind ×2, Rose Garnet ×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 15 Wind Cluster, 9 Ice Cluster, 8 Water Crystal and 3 other kinds.

The chain crosses three disciplines — Alchemist to Lv 100, Carpenter to Lv 100 and Goldsmith 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: Fulgurpine Log (8:00, 20:00), Rose Garnet Ore (0:00, 12:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Rose Garnet has the widest use: 45 recipes call for it, spanning seven of the eight crafting classes.
