Sky Rat Breeches of Fending ★★★★

Taken all the way down to base materials, one Sky Rat Breeches of Fending is 3 crafting steps deep and needs 6 intermediates — Grade 2 Vitality Dissolvent ×2, Stormcloud Cotton Cloth ×2, Griffin Leather Strap ×1 and 3 others — which resolve to 10 distinct raw materials totalling 25 units, plus 57 crystals.

That bill outweighs 9,313 of the 13,602 recipes tracked here and 1,219 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 51 are burned by the intermediates, so the real crystal cost is 14 Earth Crystal, 13 Lightning Cluster, 9 Wind Cluster and 4 other kinds.

The chain crosses four disciplines — Weaver to Lv 60, Alchemist to Lv 60, Blacksmith to Lv 60 and Leatherworker to Lv 60 — so no single class can finish it unaided.

5 of the 10 raw materials come out of the ground, and 2 of them are time-gated: Stormcloud Cotton Boll (0:00, 4:00, 8:00, 12:00, 16:00, 20:00) and Clary Sage (0:00, 20:00). The widest gap between consecutive opening times is 4 Eorzean hours, about 12 real-world minutes.

Of the intermediates, Griffin Leather Strap has the widest use: 38 recipes call for it, spanning four of the eight crafting classes.
