Titanium Gold Greatsword

Taken all the way down to base materials, one Titanium Gold Greatsword is 2 crafting steps deep and needs 4 intermediates — Titanium Gold Nugget ×2, White Gold Ingot ×2, Cobalt Tungsten Ingot ×1 and 1 other — which resolve to 7 distinct raw materials totalling 34 units, plus 64 crystals.

That bill outweighs 11,052 of the 13,602 recipes tracked here and 1,301 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 48 are burned by the intermediates, so the real crystal cost is 32 Fire Crystal, 16 Wind Crystal, 8 Earth Crystal and 1 other kind.

The chain crosses three disciplines — Blacksmith to Lv 96, Goldsmith to Lv 96 and Alchemist to Lv 95 — 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, White Gold Ingot has the widest use: 121 recipes call for it, spanning seven of the eight crafting classes.
