Cobalt Tungsten Khukuri

Taken all the way down to base materials, one Cobalt Tungsten Khukuri is 3 crafting steps deep and needs 4 intermediates — Cobalt Tungsten Ingot ×3, Pink Beryl ×1, Ruthenium Ingot ×1 and 1 other — which resolve to 6 distinct raw materials totalling 35 units, plus 71 crystals.

That bill outweighs 11,223 of the 13,602 recipes tracked here and 1,335 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 56 are burned by the intermediates, so the real crystal cost is 40 Fire Crystal, 24 Wind Crystal and 7 Earth Crystal.

The chain crosses two disciplines — Blacksmith to Lv 95 and Goldsmith to Lv 94 — 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, Cobalt Tungsten Ingot has the widest use: 105 recipes call for it, spanning six of the eight crafting classes.
