Steel Raising Hammer

Taken all the way down to base materials, one Steel Raising Hammer is 3 crafting steps deep and needs 3 intermediates — Steel Ingot ×3, Oak Lumber ×1 and Steel Plate ×1 — which resolve to 3 distinct raw materials totalling 12 units, plus 20 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 8 of those crystals go into the final step; the other 12 are burned by the intermediates, so the real crystal cost is 10 Fire Shard, 4 Earth Shard, 3 Ice Shard and 1 other kind.

The chain crosses three disciplines — Blacksmith to Lv 38, Carpenter to Lv 32 and Armorer to Lv 27 — so no single class can finish it unaided.

All 3 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.
