Alpine Inner Wall

Taken all the way down to base materials, one Alpine Inner Wall is 3 crafting steps deep and needs 5 intermediates — Cloud Mica Whetstone ×5, Mortar ×4, Rose Gold Ingot ×3 and 2 others — which resolve to 8 distinct raw materials totalling 92 units, plus 63 crystals.

That bill outweighs 13,453 of the 13,602 recipes tracked here and 2,175 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 54 are burned by the intermediates, so the real crystal cost is 48 Wind Crystal, 8 Water Shard, 4 Fire Crystal and 1 other kind.

The chain crosses two disciplines — Goldsmith to Lv 56 and Alchemist to Lv 20 — so no single class can finish it unaided.

6 of the 8 raw materials come out of the ground, and one of them is time-gated: Gold Ore (9:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Rose Gold Nugget has the widest use: 179 recipes call for it, spanning seven of the eight crafting classes.
