Koppranickel Armlets of Healing

Taken all the way down to base materials, one Koppranickel Armlets of Healing is 3 crafting steps deep and needs 3 intermediates — Koppranickel Nugget ×2, Bloodhempen Cloth ×1 and Bloodhempen Yarn ×4 — which resolve to 4 distinct raw materials totalling 20 units, plus 15 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 1,141 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 10 are burned by the intermediates, so the real crystal cost is 9 Wind Crystal, 4 Lightning Crystal and 2 Fire Crystal.

The chain crosses two disciplines — Goldsmith to Lv 61 and Weaver to Lv 61 — 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, Koppranickel Nugget has the widest use: 124 recipes call for it, spanning seven of the eight crafting classes.
