Glade Classical Window

Taken all the way down to base materials, one Glade Classical Window is 3 crafting steps deep and needs 3 intermediates — Ash Lumber ×6, Clear Glass Lens ×4 and Natron ×4 — which resolve to 4 distinct raw materials totalling 30 units, plus 28 crystals.

That bill outweighs 10,368 of the 13,602 recipes tracked here and 1,066 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 26 are burned by the intermediates, so the real crystal cost is 20 Water Shard, 7 Wind Shard and 1 Ice Shard.

The chain crosses two disciplines — Carpenter to Lv 13 and Alchemist to Lv 28 — so no single class can finish it unaided.

One intermediate outranks the result: Clear Glass Lens is a Lv 28 Alchemist recipe feeding a Lv 13 craft, so that step, not the last one, is the real gate.

All 4 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.
