Plumed Steel Hatchet

Taken all the way down to base materials, one Plumed Steel Hatchet is 2 crafting steps deep and needs 2 intermediates — Steel Ingot ×1 and Yew Lumber ×1 — which resolve to 4 distinct raw materials totalling 7 units, plus 11 crystals.

That bill outweighs 4,963 of the 13,602 recipes tracked here and 507 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 4 are burned by the intermediates, so the real crystal cost is 6 Fire Shard, 3 Earth Shard and 2 Wind Shard.

The chain crosses two disciplines — Blacksmith to Lv 35 and Carpenter to Lv 21 — so no single class can finish it unaided.

All 4 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, Steel Ingot has the widest use: 125 recipes call for it, spanning seven of the eight crafting classes.
