Ametrine Bracelet of Casting

Taken all the way down to base materials, one Ametrine Bracelet of Casting is 3 crafting steps deep and needs 3 intermediates — Ametrine ×1, High Durium Nugget ×1 and Chloroschist Whetstone ×2 — which resolve to 4 distinct raw materials totalling 17 units, plus 47 crystals.

That bill outweighs 7,161 of the 13,602 recipes tracked here and 1,025 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 32 Wind Crystal and 15 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.
