Rarefied Koppranickel Necklace

Taken all the way down to base materials, one Rarefied Koppranickel Necklace is 3 crafting steps deep and needs 4 intermediates — Koppranickel Ingot ×2, Kyanite ×1, Ruby Cotton Yarn ×1 and 1 other — which resolve to 6 distinct raw materials totalling 26 units, plus 23 crystals.

That bill outweighs 9,543 of the 13,602 recipes tracked here and 1,562 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 19 Wind Crystal, 3 Fire Crystal and 1 Lightning Crystal.

The chain crosses two disciplines — Goldsmith to Lv 64 and Weaver to Lv 62 — so no single class can finish it unaided.

All 6 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.
