Small Imitation Window

Taken all the way down to base materials, one Small Imitation Window is 3 crafting steps deep and needs 5 intermediates — Oak Lumber ×3, Clear Glass Lens ×2, Steel Rivets ×1 and 2 others — which resolve to 6 distinct raw materials totalling 18 units, plus 30 crystals.

That bill outweighs 7,380 of the 13,602 recipes tracked here and 740 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 12 Wind Shard, 10 Water Shard, 5 Fire Shard and 1 other kind.

The chain crosses three disciplines — Carpenter to Lv 32, Blacksmith to Lv 29 and Alchemist to Lv 28 — 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, Steel Ingot has the widest use: 125 recipes call for it, spanning seven of the eight crafting classes.
