Ametrine Armillae of Crafting

Taken all the way down to base materials, one Ametrine Armillae of Crafting is 3 crafting steps deep and needs 4 intermediates — High Durium Nugget ×2, Ametrine ×1, Gaja Leather ×1 and 1 other — which resolve to 6 distinct raw materials totalling 24 units, plus 55 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 1,346 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 40 are burned by the intermediates, so the real crystal cost is 24 Wind Crystal, 23 Fire Crystal and 8 Earth Crystal.

The chain crosses three disciplines — Goldsmith to Lv 81, Blacksmith to Lv 81 and Leatherworker to Lv 81 — so no single class can finish it unaided.

5 of the 6 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Of the intermediates, High Durium Nugget has the widest use: 87 recipes call for it, spanning five of the eight crafting classes.
