Highland Ornate Door

Taken all the way down to base materials, one Highland Ornate Door is 3 crafting steps deep and needs 4 intermediates — Titanium Nugget ×5, Dark Chestnut Lumber ×3, Clear Glass Lens ×2 and 1 other — which resolve to 7 distinct raw materials totalling 56 units, plus 53 crystals.

That bill outweighs 12,997 of the 13,602 recipes tracked here and 1,379 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 42 are burned by the intermediates, so the real crystal cost is 20 Fire Crystal, 12 Wind Crystal, 10 Water Shard and 2 other kinds.

The chain crosses four disciplines — Armorer to Lv 60, Blacksmith to Lv 54, Carpenter to Lv 54 and Alchemist to Lv 28 — so no single class can finish it unaided.

All 7 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.
