Rarefied Kudzu Hat

Taken all the way down to base materials, one Rarefied Kudzu Hat is 3 crafting steps deep and needs 4 intermediates — Kudzu Cloth ×2, Durium Nugget ×1, Kudzu Thread ×4 and 1 other — which resolve to 4 distinct raw materials totalling 21 units, plus 23 crystals.

That bill outweighs 8,152 of the 13,602 recipes tracked here and 1,065 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 14 are burned by the intermediates, so the real crystal cost is 15 Lightning Crystal and 8 Wind Crystal.

The chain crosses two disciplines — Weaver to Lv 66 and Goldsmith to Lv 64 — so no single class can finish it unaided.

All 4 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

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