Cluster Lamp

Taken all the way down to base materials, one Cluster Lamp is 2 crafting steps deep and needs 2 intermediates — Annite Whetstone ×4 and Bluespirit Tile ×4 — which resolve to 4 distinct raw materials totalling 38 units, plus 66 crystals.

That bill outweighs 11,698 of the 13,602 recipes tracked here and 1,875 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 60 are burned by the intermediates, so the real crystal cost is 32 Wind Crystal, 28 Fire Crystal, 3 Fire Cluster and 1 other kind.

The chain crosses two disciplines — Goldsmith to Lv 90 and Blacksmith to Lv 74 — so no single class can finish it unaided.

All 4 raw materials are gathered, and one of them is time-gated: Prismstone (4:00, 16:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Annite Whetstone has the widest use: 96 recipes call for it, spanning four of the eight crafting classes.
