Titanium Alembic

Taken all the way down to base materials, one Titanium Alembic is 3 crafting steps deep and needs 6 intermediates — Titanium Ingot ×2, Titanium Rivets ×2, Electrum Ingot ×1 and 3 others — which resolve to 6 distinct raw materials totalling 46 units, plus 58 crystals.

That bill outweighs 12,540 of the 13,602 recipes tracked here and 1,324 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 49 are burned by the intermediates, so the real crystal cost is 34 Fire Crystal, 10 Wind Crystal, 5 Ice Crystal and 2 other kinds.

The chain crosses three disciplines — Armorer to Lv 57, Blacksmith to Lv 56 and Goldsmith to Lv 56 — so no single class can finish it unaided.

All 6 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, Electrum Ingot has the widest use: 234 recipes call for it, spanning seven of the eight crafting classes.
