Highland Interior Wall

Taken all the way down to base materials, one Highland Interior Wall is 3 crafting steps deep and needs 4 intermediates — Cloud Mica Whetstone ×5, Dark Chestnut Lumber ×5, Mortar ×4 and 1 other — which resolve to 6 distinct raw materials totalling 64 units, plus 64 crystals.

That bill outweighs 13,221 of the 13,602 recipes tracked here and 1,562 of the 1,591 Alchemist ones, and 337 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 53 are burned by the intermediates, so the real crystal cost is 45 Wind Crystal, 8 Water Shard, 6 Water Crystal and 1 other kind.

The chain crosses three disciplines — Alchemist to Lv 60, Goldsmith to Lv 56 and Carpenter to Lv 54 — so no single class can finish it unaided.

All 6 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.
