Highland Classical Window

Taken all the way down to base materials, one Highland Classical Window is 3 crafting steps deep and needs 3 intermediates — Clear Glass Lens ×4, Dark Chestnut Lumber ×4 and Natron ×4 — which resolve to 5 distinct raw materials totalling 34 units, plus 47 crystals.

That bill outweighs 11,052 of the 13,602 recipes tracked here and 1,407 of the 1,591 Alchemist ones, and 337 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 36 are burned by the intermediates, so the real crystal cost is 20 Water Shard, 16 Wind Crystal, 6 Water Crystal and 1 other kind.

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

All 5 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, Clear Glass Lens has the widest use: 96 recipes call for it, spanning six of the eight crafting classes.
