Highland Classical Door

Taken all the way down to base materials, one Highland Classical Door is 3 crafting steps deep and needs 5 intermediates — Hallowed Chestnut Lumber ×4, Titanium Nugget ×3, Cut Stone ×2 and 2 others — which resolve to 7 distinct raw materials totalling 59 units, plus 80 crystals.

That bill outweighs 13,079 of the 13,602 recipes tracked here and 1,413 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 69 are burned by the intermediates, so the real crystal cost is 42 Wind Crystal, 15 Water Crystal, 12 Fire Crystal and 2 other kinds.

The chain crosses four disciplines — Carpenter to Lv 60, Alchemist to Lv 56, Blacksmith to Lv 54 and Goldsmith to Lv 30 — so no single class can finish it unaided.

All 7 raw materials are gathered, and one of them is time-gated: Abalathian Mistletoe (6:00, 18:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Titanium Nugget has the widest use: 112 recipes call for it, spanning six of the eight crafting classes.
