Pactmaker's Boots of Gathering ★★

Taken all the way down to base materials, one Pactmaker's Boots of Gathering is 2 crafting steps deep and needs 3 intermediates — Hannish Fiber ×3, Amynodon Leather ×2 and Ophiotauros Leather ×1 — which resolve to 8 distinct raw materials totalling 37 units, plus 44 crystals.

That bill outweighs 11,564 of the 13,602 recipes tracked here and 1,713 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 38 are burned by the intermediates, so the real crystal cost is 9 Earth Cluster, 9 Lightning Cluster, 9 Water Cluster and 2 other kinds.

The chain crosses two disciplines — Leatherworker to Lv 90 and Alchemist to Lv 90 — so no single class can finish it unaided.

3 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Rime Dolomite (0:00, 12:00) and Thavnairian Corn (8:00, 20:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Ophiotauros Leather has the widest use: 153 recipes call for it, spanning seven of the eight crafting classes.
