Frontier Pumps ★★★★

Taken all the way down to base materials, one Frontier Pumps is 2 crafting steps deep and needs 2 intermediates — Thylacoleo Leather ×2 and Silver Beech Lumber ×1 — which resolve to 5 distinct raw materials totalling 19 units, plus 32 crystals.

That bill outweighs 7,589 of the 13,602 recipes tracked here and 958 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 9 Wind Cluster, 7 Earth Crystal, 7 Wind Crystal and 2 other kinds.

The chain crosses two disciplines — Leatherworker to Lv 80 and Carpenter 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: Silver Beech Log (6:00, 18:00) and Wattle Petribark (0:00, 12:00). The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

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