Titanbronze Sledgehammer

Taken all the way down to base materials, one Titanbronze Sledgehammer is 2 crafting steps deep and needs 2 intermediates — Titanbronze Ingot ×2 and Sandteak Lumber ×1 — which resolve to 3 distinct raw materials totalling 14 units, plus 35 crystals.

That bill outweighs 6,557 of the 13,602 recipes tracked here and 699 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 21 are burned by the intermediates, so the real crystal cost is 21 Fire Crystal, 7 Earth Crystal and 7 Wind Crystal.

The chain crosses two disciplines — Blacksmith to Lv 77 and Carpenter to Lv 76 — so no single class can finish it unaided.

All 3 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, Titanbronze Ingot has the widest use: 63 recipes call for it, spanning six of the eight crafting classes.
