Rhea Cloth ★★

Taken all the way down to base materials, one Rhea Cloth is 2 crafting steps deep and needs 1 intermediate — Bloodhempen Yarn ×1 — which resolves to 3 distinct raw materials totalling 10 units, plus 5 crystals.

That bill outweighs 5,754 of the 13,602 recipes tracked here and 695 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 1 are burned by the intermediates, so the real crystal cost is 2 Lightning Cluster, 2 Wind Cluster and 1 Lightning Crystal.

Every step is Weaver work, from a Lv 61 intermediate up to the Lv 70 finish, so one class covers the whole chain.

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

Rhea Cloth is itself consumed by 21 further recipes, spanning six of the eight crafting classes.
