Frontier Jacket ★★★★

Taken all the way down to base materials, one Frontier Jacket is 2 crafting steps deep and needs 2 intermediates — Thylacoleo Leather ×3 and Saffron Cloth ×1 — which resolve to 5 distinct raw materials totalling 26 units, plus 38 crystals.

That bill outweighs 9,543 of the 13,602 recipes tracked here and 1,336 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 12 Wind Cluster, 9 Earth Cluster, 7 Earth Crystal and 2 other kinds.

The chain crosses two disciplines — Leatherworker to Lv 80 and Weaver to Lv 80 — so no single class can finish it unaided.

2 of the 5 raw materials come out of the ground, and 2 of them are time-gated: Raindrop Cotton Boll (10:00, 22:00) and Wattle Petribark (0:00, 12:00). The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

Of the intermediates, Thylacoleo Leather has the widest use: 35 recipes call for it, spanning five of the eight crafting classes.
