Cobalt Tungsten Scimitar

Taken all the way down to base materials, one Cobalt Tungsten Scimitar is 3 crafting steps deep and needs 4 intermediates — Ceiba Lumber ×1, Cobalt Tungsten Ingot ×1, Pink Beryl ×1 and 1 other — which resolve to 5 distinct raw materials totalling 22 units, plus 55 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 917 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 40 are burned by the intermediates, so the real crystal cost is 32 Wind Crystal, 16 Fire Crystal and 7 Earth Crystal.

The chain crosses three disciplines — Blacksmith to Lv 94, Goldsmith to Lv 94 and Carpenter to Lv 92 — so no single class can finish it unaided.

All 5 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.
