Ovim Wool Yarn

Taken all the way down to base materials, a batch of 3 Ovim Wool Yarn is 2 crafting steps deep and needs 1 intermediate — Refined Natron ×1 — which resolves to 3 distinct raw materials totalling 6 units, plus 10 crystals.

That bill outweighs 4,542 of the 13,602 recipes tracked here and 495 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 7 are burned by the intermediates, so the real crystal cost is 7 Water Crystal and 3 Lightning Crystal.

The chain crosses two disciplines — Weaver to Lv 76 and Alchemist to Lv 76 — so no single class can finish it unaided.

2 of the 3 raw materials come out of the ground, and one of them is time-gated: Ala Mhigan Salt Crystal (0:00, 12:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Ovim Wool Yarn is itself consumed by 16 further recipes, spanning four of the eight crafting classes.
