Cobalt Raising Hammer

Taken all the way down to base materials, one Cobalt Raising Hammer is 3 crafting steps deep and needs 4 intermediates — Cobalt Ingot ×4, Cobalt Plate ×1, Cobalt Rivets ×1 and 1 other — which resolve to 3 distinct raw materials totalling 15 units, plus 47 crystals.

That bill outweighs 6,735 of the 13,602 recipes tracked here and 730 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 36 are burned by the intermediates, so the real crystal cost is 31 Fire Shard, 6 Wind Shard, 5 Earth Shard and 1 other kind.

The chain crosses three disciplines — Blacksmith to Lv 47, Carpenter to Lv 45 and Armorer to Lv 43 — 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, Cobalt Ingot has the widest use: 145 recipes call for it, spanning seven of the eight crafting classes.
