Mellow Mog Lamp ★★

Taken all the way down to base materials, one Mellow Mog Lamp is 3 crafting steps deep and needs 5 intermediates — Palladium Nugget ×3, Tempered Glass ×3, Silvergrace Ingot ×2 and 2 others — which resolve to 12 distinct raw materials totalling 48 units, plus 74 crystals.

That bill outweighs 12,691 of the 13,602 recipes tracked here and 2,043 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 70 are burned by the intermediates, so the real crystal cost is 21 Lightning Crystal, 21 Water Crystal, 18 Wind Crystal and 3 other kinds.

The chain crosses two disciplines — Goldsmith to Lv 70 and Alchemist to Lv 60 — so no single class can finish it unaided.

8 of the 12 raw materials come out of the ground, and one of them is time-gated: Silvergrace Ore (8:00, 20:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Palladium Nugget has the widest use: 129 recipes call for it, spanning seven of the eight crafting classes.
