Ametrine Choker of Healing

Taken all the way down to base materials, one Ametrine Choker of Healing is 3 crafting steps deep and needs 3 intermediates — High Durium Nugget ×2, Ametrine ×1 and Chloroschist Whetstone ×1 — which resolve to 4 distinct raw materials totalling 19 units, plus 47 crystals.

That bill outweighs 7,589 of the 13,602 recipes tracked here and 1,074 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 24 Wind Crystal and 23 Fire Crystal.

The chain crosses two disciplines — Goldsmith to Lv 81 and Blacksmith to Lv 81 — 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, High Durium Nugget has the widest use: 87 recipes call for it, spanning five of the eight crafting classes.
