Iron Raising Hammer

Taken all the way down to base materials, one Iron Raising Hammer is 3 crafting steps deep and needs 3 intermediates — Iron Ingot ×3, Iron Plate ×1 and Walnut Lumber ×1 — which resolve to 2 distinct raw materials totalling 12 units, plus 10 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 4 of those crystals go into the final step; the other 6 are burned by the intermediates, so the real crystal cost is 5 Fire Shard, 2 Earth Shard, 2 Wind Shard and 1 other kind.

The chain crosses three disciplines — Blacksmith to Lv 26, Carpenter to Lv 25 and Armorer to Lv 14 — so no single class can finish it unaided.

Both raw materials are gathered, and no spot for either is timed, so nothing in the tree waits on the Eorzean clock.

Iron Raising Hammer is itself consumed by 1 further recipe, all of them Blacksmith recipes.
