Highland Flooring

Taken all the way down to base materials, one Highland Flooring is 2 crafting steps deep and needs 2 intermediates — Dark Chestnut Lumber ×10 and Cut Stone ×4 — which resolve to 2 distinct raw materials totalling 66 units, plus 63 crystals.

That bill outweighs 13,242 of the 13,602 recipes tracked here and 1,449 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 52 are burned by the intermediates, so the real crystal cost is 46 Wind Crystal, 12 Wind Shard and 5 Ice Crystal.

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

Both raw materials are gathered, and no spot for either is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Cut Stone has the widest use: 103 recipes call for it, spanning six of the eight crafting classes.
