Amdapori Wall Lantern

Taken all the way down to base materials, one Amdapori Wall Lantern is 2 crafting steps deep and needs 2 intermediates — Mythril Ingot ×4 and Darksteel Nugget ×2 — which resolve to 4 distinct raw materials totalling 24 units, plus 34 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 1,346 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 22 are burned by the intermediates, so the real crystal cost is 22 Fire Shard, 6 Fire Crystal and 6 Wind Shard.

The chain crosses two disciplines — Goldsmith to Lv 50 and Blacksmith to Lv 50 — so no single class can finish it unaided.

2 of the 4 raw materials come out of the ground, and one of them is time-gated: Darksteel Ore (1:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Mythril Ingot has the widest use: 135 recipes call for it, spanning seven of the eight crafting classes.
