Highland Mansion Wall (Wood)

Taken all the way down to base materials, one Highland Mansion Wall (Wood) is 3 crafting steps deep and needs 6 intermediates — Clear Glass Lens ×15, Mythrite Ingot ×15, Roof Tile ×15 and 3 others — which resolve to 10 distinct raw materials totalling 310 units, plus 260 crystals.

That bill outweighs 13,593 of the 13,602 recipes tracked here and 1,551 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 40 of those crystals go into the final step; the other 220 are burned by the intermediates, so the real crystal cost is 90 Fire Crystal, 90 Water Shard, 60 Wind Crystal and 1 other kind.

The chain crosses three disciplines — Carpenter to Lv 60, Blacksmith to Lv 52 and Alchemist to Lv 28 — so no single class can finish it unaided.

All 10 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, Mythrite Nugget has the widest use: 102 recipes call for it, spanning seven of the eight crafting classes.
