Titanium Gold Alembic

Taken all the way down to base materials, one Titanium Gold Alembic is 2 crafting steps deep and needs 2 intermediates — Titanium Gold Nugget ×2 and White Gold Ingot ×2 — which resolve to 4 distinct raw materials totalling 24 units, plus 48 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 881 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 16 Fire Crystal, 16 Wind Crystal, 8 Earth Crystal and 1 other kind.

The chain crosses three disciplines — Armorer to Lv 97, Blacksmith to Lv 96 and Goldsmith to Lv 96 — 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, White Gold Ingot has the widest use: 121 recipes call for it, spanning seven of the eight crafting classes.
