Amaurotine Interior Wall

Taken all the way down to base materials, one Amaurotine Interior Wall is 3 crafting steps deep and needs 5 intermediates — Annite Whetstone ×5, Onyx ×5, Mortar ×4 and 2 others — which resolve to 7 distinct raw materials totalling 74 units, plus 134 crystals.

That bill outweighs 13,358 of the 13,602 recipes tracked here and 2,162 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 118 are burned by the intermediates, so the real crystal cost is 118 Wind Crystal, 8 Fire Crystal and 8 Water Shard.

The chain crosses two disciplines — Goldsmith to Lv 90 and Alchemist to Lv 20 — so no single class can finish it unaided.

All 7 raw materials are gathered, and one of them is time-gated: Raw Onyx (0:00, 12:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Mortar has the widest use: 140 recipes call for it, spanning six of the eight crafting classes.
