Cobalt Hatchet

Taken all the way down to base materials, one Cobalt Hatchet is 2 crafting steps deep and needs 3 intermediates — Brass Ingot ×1, Cobalt Ingot ×1 and Mahogany Lumber ×1 — which resolve to 5 distinct raw materials totalling 9 units, plus 21 crystals.

That bill outweighs 5,492 of the 13,602 recipes tracked here and 597 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 11 are burned by the intermediates, so the real crystal cost is 10 Fire Shard, 6 Wind Shard and 5 Earth Shard.

The chain crosses three disciplines — Blacksmith to Lv 43, Carpenter to Lv 39 and Goldsmith to Lv 14 — 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 Ingot has the widest use: 145 recipes call for it, spanning seven of the eight crafting classes.
