The Fae's Crown Rod ★★

Taken all the way down to base materials, one The Fae's Crown Rod is 3 crafting steps deep and needs 4 intermediates — Sandalwood Lumber ×3, Tungsten Steel Ingot ×2, Onyx ×1 and 1 other — which resolve to 8 distinct raw materials totalling 45 units, plus 38 crystals.

That bill outweighs 12,451 of the 13,602 recipes tracked here and 1,317 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, Blacksmith to Lv 80 and Goldsmith to Lv 80 — so no single class can finish it unaided.

4 of the 8 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 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Tungsten Steel Ingot has the widest use: 113 recipes call for it, spanning six of the eight crafting classes.
