Kudzu Hat of Healing

Taken all the way down to base materials, one Kudzu Hat of Healing is 3 crafting steps deep and needs 5 intermediates — Kudzu Cloth ×2, Durium Nugget ×1, Grade 1 Reisui of Mind ×1 and 2 others — which resolve to 8 distinct raw materials totalling 27 units, plus 25 crystals.

That bill outweighs 9,763 of the 13,602 recipes tracked here and 1,307 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 14 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.
