Molybdenum Alembic

Taken all the way down to base materials, one Molybdenum Alembic is 3 crafting steps deep and needs 4 intermediates — Molybdenum Ingot ×3, Palladium Nugget ×1, Tama-hagane Ingot ×1 and 1 other — which resolve to 7 distinct raw materials totalling 29 units, plus 40 crystals.

That bill outweighs 10,170 of the 13,602 recipes tracked here and 1,028 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 29 are burned by the intermediates, so the real crystal cost is 24 Fire Crystal, 6 Ice Crystal, 5 Earth Crystal and 1 other kind.

The chain crosses three disciplines — Armorer to Lv 70, Blacksmith to Lv 68 and Goldsmith to Lv 68 — so no single class can finish it unaided.

All 7 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, Palladium Nugget has the widest use: 129 recipes call for it, spanning seven of the eight crafting classes.
