Highland Cottage Roof (Wood)

Taken all the way down to base materials, one Highland Cottage Roof (Wood) is 3 crafting steps deep and needs 7 intermediates — Dark Chestnut Lumber ×10, Iron Joint Plate ×10, Mortar ×10 and 4 others — which resolve to 8 distinct raw materials totalling 150 units, plus 120 crystals.

That bill outweighs 13,530 of the 13,602 recipes tracked here and 1,534 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 20 of those crystals go into the final step; the other 100 are burned by the intermediates, so the real crystal cost is 52 Wind Crystal, 25 Water Shard, 15 Wind Shard and 3 other kinds.

The chain crosses five disciplines — Carpenter to Lv 60, Goldsmith to Lv 30, Alchemist to Lv 20, Blacksmith to Lv 16 and Armorer to Lv 15 — so no single class can finish it unaided.

All 8 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, Mortar has the widest use: 140 recipes call for it, spanning six of the eight crafting classes.
