Iron Chocobotail Saw

Taken all the way down to base materials, one Iron Chocobotail Saw is 3 crafting steps deep and needs 4 intermediates — Iron Ingot ×2, Brass Ingot ×1, Iron Rivets ×1 and 1 other — which resolve to 4 distinct raw materials totalling 12 units, plus 11 crystals.

That bill outweighs 6,221 of the 13,602 recipes tracked here and 674 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 6 are burned by the intermediates, so the real crystal cost is 6 Fire Shard, 3 Wind Shard and 2 Earth Shard.

The chain crosses three disciplines — Blacksmith to Lv 28, Carpenter to Lv 25 and Goldsmith to Lv 14 — 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, Walnut Lumber has the widest use: 128 recipes call for it, spanning eight of the eight crafting classes.
