Rubellux Rod ★★

Taken all the way down to base materials, one Rubellux Rod is 3 crafting steps deep and needs 4 intermediates — Sandalwood Lumber ×3, Pliable Glass Fiber ×2, Onyx ×1 and 1 other — which resolve to 9 distinct raw materials totalling 43 units, plus 38 crystals.

That bill outweighs 12,178 of the 13,602 recipes tracked here and 1,293 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 34 are burned by the intermediates, so the real crystal cost is 14 Wind Crystal, 8 Ice Cluster, 8 Wind Cluster and 2 other kinds.

The chain crosses three disciplines — Carpenter to Lv 80, Alchemist to Lv 80 and Goldsmith to Lv 80 — so no single class can finish it unaided.

4 of the 9 raw materials come out of the ground, and 3 of them are time-gated: Raw Onyx (0:00, 12:00), Sandalwood Log (2:00, 14:00) and 1 other. The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

Of the intermediates, Onyx has the widest use: 61 recipes call for it, spanning four of the eight crafting classes.
