Sarnga Limb ★★

Taken all the way down to base materials, one Sarnga Limb is 3 crafting steps deep and needs 3 intermediates — Darksteel Nugget ×2, Treated Spruce Lumber ×1 and Spruce Lumber ×2 — which resolve to 3 distinct raw materials totalling 21 units, plus 15 crystals.

That bill outweighs 8,152 of the 13,602 recipes tracked here and 815 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 13 are burned by the intermediates, so the real crystal cost is 6 Fire Crystal, 6 Wind Crystal, 2 Wind Cluster and 1 other kind.

The chain crosses two disciplines — Carpenter to Lv 50 and Blacksmith to Lv 50 — so no single class can finish it unaided.

2 of the 3 raw materials come out of the ground, and 2 of them are time-gated: Darksteel Ore (1:00) and Spruce Log (9:00). The widest gap between consecutive opening times is 16 Eorzean hours, about 47 real-world minutes.

Sarnga Limb is itself consumed by 1 further recipe, all of them Carpenter recipes.
