Titanic Cragsoul Lamp ★★

Taken all the way down to base materials, one Titanic Cragsoul Lamp is 3 crafting steps deep and needs 3 intermediates — Darksteel Nugget ×4, Rose Gold Ingot ×2 and Rose Gold Nugget ×4 — which resolve to 7 distinct raw materials totalling 53 units, plus 36 crystals.

That bill outweighs 12,925 of the 13,602 recipes tracked here and 2,088 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 26 are burned by the intermediates, so the real crystal cost is 12 Fire Crystal, 12 Wind Crystal, 10 Earth Crystal and 1 other kind.

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

3 of the 7 raw materials come out of the ground, and 2 of them are time-gated: Darksteel Ore (1:00) and Gold Ore (9:00). The widest gap between consecutive opening times is 16 Eorzean hours, about 47 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.
