Marid Leather Bolero of Crafting

Taken all the way down to base materials, one Marid Leather Bolero of Crafting is 4 crafting steps deep and needs 9 intermediates — Marid Leather ×2, Carnelian ×1, Durium Ingot ×1 and 6 others — which resolve to 12 distinct raw materials totalling 39 units, plus 54 crystals.

That bill outweighs 11,756 of the 13,602 recipes tracked here and 1,756 of the 1,844 Leatherworker ones, and 1 recipe nests deeper.

Only 9 of those crystals go into the final step; the other 45 are burned by the intermediates, so the real crystal cost is 23 Wind Crystal, 15 Earth Crystal, 7 Lightning Crystal and 2 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 67, Alchemist to Lv 66, Goldsmith to Lv 66 and Weaver to Lv 66 — so no single class can finish it unaided.

9 of the 12 raw materials match a gathering node, none of them timed; the other 3 come from vendors, drops or content this site does not track.

Of the intermediates, Durium Nugget has the widest use: 142 recipes call for it, spanning seven of the eight crafting classes.
