Electrum Head Knife

Taken all the way down to base materials, one Electrum Head Knife is 2 crafting steps deep and needs 4 intermediates — Basilisk Whetstone ×1, Cobalt Ingot ×1, Electrum Ingot ×1 and 1 other — which resolve to 5 distinct raw materials totalling 11 units, plus 32 crystals.

That bill outweighs 5,999 of the 13,602 recipes tracked here and 661 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

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

The chain crosses three disciplines — Blacksmith to Lv 46, 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.
