Rod of Nihility Display ★★★★

Taken all the way down to base materials, one Rod of Nihility Display is 3 crafting steps deep and needs 5 intermediates — Double Duraluminum Ingot ×2, Rose Garnet ×2, Black Star ×1 and 2 others — which resolve to 8 distinct raw materials totalling 38 units, plus 54 crystals.

That bill outweighs 11,698 of the 13,602 recipes tracked here and 1,875 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 48 are burned by the intermediates, so the real crystal cost is 15 Fire Cluster, 9 Wind Cluster, 8 Fire Crystal and 3 other kinds.

The chain crosses three disciplines — Goldsmith to Lv 100, Blacksmith to Lv 100 and Alchemist to Lv 95 — so no single class can finish it unaided.

5 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Dense Aluminum Ore (10:00, 22:00) and Rose Garnet Ore (0:00, 12:00). The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

Of the intermediates, Ra'Kaznar Ingot has the widest use: 166 recipes call for it, spanning seven of the eight crafting classes.
