Kudzu Longkilt of Fending

Taken all the way down to base materials, one Kudzu Longkilt of Fending is 3 crafting steps deep and needs 5 intermediates — Kudzu Cloth ×3, Grade 1 Reisui of Vitality ×2, Durium Nugget ×1 and 2 others — which resolve to 8 distinct raw materials totalling 31 units, plus 29 crystals.

That bill outweighs 10,578 of the 13,602 recipes tracked here and 1,468 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 22 are burned by the intermediates, so the real crystal cost is 18 Lightning Crystal, 7 Wind Crystal and 4 Water Crystal.

The chain crosses three disciplines — Weaver to Lv 64, Goldsmith to Lv 64 and Alchemist to Lv 63 — so no single class can finish it unaided.

All 8 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.
