Holy Cedar Lumber

Taken all the way down to base materials, one Holy Cedar Lumber is 2 crafting steps deep and needs 2 intermediates — Holy Water ×2 and Cedar Lumber ×1 — which resolve to 3 distinct raw materials totaling 9 units, plus 9 crystals.

That bill outweighs 5,492 of the 13,602 recipes tracked here and 549 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 6 are burned by the intermediates, so the real crystal cost is 6 Wind Crystal and 3 Water Crystal.

The chain crosses two disciplines — Carpenter to Lv 52 and Alchemist to Lv 52 — so no single class can finish it unaided.

All 3 raw materials are gathered, and one of them is time-gated: Dravanian Mistletoe (0:00, 12:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Holy Cedar Lumber is itself consumed by 26 further recipes, spanning five of the eight crafting classes.
