Lord of Levin Lamp ★★★

Taken all the way down to base materials, one Lord of Levin Lamp is 3 crafting steps deep and needs 3 intermediates — Wolfram Ingot ×3, Vanya Silk ×2 and Silk Thread ×4 — which resolve to 8 distinct raw materials totalling 36 units, plus 29 crystals.

That bill outweighs 11,383 of the 13,602 recipes tracked here and 1,369 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 17 are burned by the intermediates, so the real crystal cost is 18 Lightning Crystal, 6 Fire Cluster, 3 Earth Cluster and 1 other kind.

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

4 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Ferberite (3:00) and Silkworm Cocoon (1:00). The widest gap between consecutive opening times is 22 Eorzean hours, about 64 real-world minutes.

Of the intermediates, Silk Thread has the widest use: 175 recipes call for it, spanning six of the eight crafting classes.
