Electrum Lapidary Hammer

Taken all the way down to base materials, one Electrum Lapidary Hammer is 3 crafting steps deep and needs 5 intermediates — Cobalt Ingot ×2, Cobalt Rivets ×1, Electrum Ingot ×1 and 2 others — which resolve to 5 distinct raw materials totalling 14 units, plus 42 crystals.

That bill outweighs 6,557 of the 13,602 recipes tracked here and 699 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 31 are burned by the intermediates, so the real crystal cost is 21 Fire Shard, 16 Wind Shard and 5 Earth Shard.

The chain crosses three disciplines — Blacksmith to Lv 47, Carpenter to Lv 45 and Goldsmith to Lv 42 — so no single class can finish it unaided.

All 5 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, Electrum Ingot has the widest use: 234 recipes call for it, spanning seven of the eight crafting classes.
