Codex of Sanctifying Light ★★

Taken all the way down to base materials, one Codex of Sanctifying Light is 2 crafting steps deep and needs 3 intermediates — Mempisang Lumber ×3, Rhodium Ingot ×2 and Enchanted Manganese Ink ×1 — which resolve to 9 distinct raw materials totalling 45 units, plus 44 crystals.

That bill outweighs 12,451 of the 13,602 recipes tracked here and 1,504 of the 1,591 Alchemist ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 38 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 90, Carpenter to Lv 90 and Goldsmith to Lv 90 — so no single class can finish it unaided.

4 of the 9 raw materials come out of the ground, and 2 of them are time-gated: Mempisang Log (6:00, 18:00) and Rhodium Sand (4:00, 16:00). The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

Of the intermediates, Rhodium Ingot has the widest use: 53 recipes call for it, spanning seven of the eight crafting classes.
