Marimo Lamp

Taken all the way down to base materials, one Marimo Lamp is 3 crafting steps deep and needs 3 intermediates — Hardsilver Nugget ×3, Growth Formula Epsilon ×1 and Quicksilver ×1 — which resolve to 7 distinct raw materials totalling 28 units, plus 24 crystals.

That bill outweighs 9,936 of the 13,602 recipes tracked here and 1,645 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 8 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 16 Wind Crystal, 4 Fire Crystal, 3 Water Crystal and 1 other kind.

The chain crosses two disciplines — Goldsmith to Lv 55 and Alchemist to Lv 51 — so no single class can finish it unaided.

6 of the 7 raw materials come out of the ground, and 2 of them are time-gated: Thavnairian Mistletoe (17:00) and Volcanic Rock Salt (17:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Hardsilver Nugget has the widest use: 88 recipes call for it, spanning seven of the eight crafting classes.
