Highland Wooden Door

Taken all the way down to base materials, one Highland Wooden Door is 2 crafting steps deep and needs 3 intermediates — Dark Chestnut Lumber ×5, Titanium Nugget ×3 and Cut Stone ×2 — which resolve to 5 distinct raw materials totalling 52 units, plus 49 crystals.

That bill outweighs 12,890 of the 13,602 recipes tracked here and 1,366 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 38 are burned by the intermediates, so the real crystal cost is 26 Wind Crystal, 12 Fire Crystal, 6 Wind Shard and 1 other kind.

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

All 5 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

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