Order of Nald'thal Lectern ★★★★

Taken all the way down to base materials, one Order of Nald'thal Lectern is 2 crafting steps deep and needs 4 intermediates — Ebony Lumber ×6, Bronze Ingot ×4, Lavender Oil ×4 and 1 other — which resolve to 7 distinct raw materials totalling 90 units, plus 38 crystals.

That bill outweighs 13,445 of the 13,602 recipes tracked here and 1,498 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 34 are burned by the intermediates, so the real crystal cost is 14 Ice Cluster, 14 Wind Cluster, 6 Fire Shard and 1 other kind.

The chain crosses four disciplines — Carpenter to Lv 50, Goldsmith to Lv 23, Culinarian to Lv 16 and Blacksmith to Lv 1 — so no single class can finish it unaided.

5 of the 7 raw materials come out of the ground, and one of them is time-gated: Ebony Log (4:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Bronze Ingot has the widest use: 76 recipes call for it, spanning six of the eight crafting classes.
