Archaeoskin Halfboots

Taken all the way down to base materials, one Archaeoskin Halfboots is 2 crafting steps deep and needs 3 intermediates — Archaeornis Leather ×1, Rubber ×1 and Silver Ingot ×1 — which resolve to 4 distinct raw materials totalling 8 units, plus 11 crystals.

That bill outweighs 5,254 of the 13,602 recipes tracked here and 636 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 6 are burned by the intermediates, so the real crystal cost is 6 Earth Crystal, 2 Wind Crystal, 2 Wind Shard and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 51, Goldsmith to Lv 23 and Alchemist to Lv 7 — so no single class can finish it unaided.

3 of the 4 raw materials come out of the ground, and one of them is time-gated: Coerthan Tea Leaves (0:00, 8:00, 10:00, 12:00, 20:00, 22:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Rubber has the widest use: 191 recipes call for it, spanning four of the eight crafting classes.
