Gliderskin Gloves of Striking

Taken all the way down to base materials, one Gliderskin Gloves of Striking is 3 crafting steps deep and needs 4 intermediates — Green Glider Leather ×2, Iridescent Silk ×1, Silk Thread ×1 and 1 other — which resolve to 5 distinct raw materials totalling 18 units, plus 33 crystals.

That bill outweighs 7,380 of the 13,602 recipes tracked here and 928 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 21 are burned by the intermediates, so the real crystal cost is 18 Earth Crystal, 9 Lightning Crystal and 6 Wind Crystal.

The chain crosses two disciplines — Leatherworker to Lv 72 and Weaver to Lv 72 — so no single class can finish it unaided.

4 of the 5 raw materials come out of the ground, and one of them is time-gated: Silkworm Cocoon (1:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Silk Thread has the widest use: 175 recipes call for it, spanning six of the eight crafting classes.
