Odder Otter Bench ★★

Taken all the way down to base materials, one Odder Otter Bench is 2 crafting steps deep and needs 3 intermediates — Black Willow Lumber ×3, Oroshigane Ingot ×3 and Cedar Lumber ×2 — which resolve to 8 distinct raw materials totalling 42 units, plus 30 crystals.

That bill outweighs 12,044 of the 13,602 recipes tracked here and 1,260 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 26 are burned by the intermediates, so the real crystal cost is 12 Fire Crystal, 6 Ice Cluster, 6 Wind Cluster and 1 other kind.

The chain crosses two disciplines — Carpenter to Lv 70 and Blacksmith to Lv 64 — so no single class can finish it unaided.

4 of the 8 raw materials come out of the ground, and one of them is time-gated: Black Willow Log (4:00, 16:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Oroshigane Ingot has the widest use: 114 recipes call for it, spanning six of the eight crafting classes.
