Electrum Monocle

Taken all the way down to base materials, one Electrum Monocle is 3 crafting steps deep and needs 6 intermediates — Aquamarine ×1, Brass Rings ×1, Clear Glass Lens ×1 and 3 others — which resolve to 7 distinct raw materials totalling 11 units, plus 26 crystals.

That bill outweighs 5,999 of the 13,602 recipes tracked here and 839 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 15 are burned by the intermediates, so the real crystal cost is 16 Wind Shard, 5 Fire Shard and 5 Water Shard.

The chain crosses two disciplines — Goldsmith to Lv 45 and Alchemist to Lv 28 — so no single class can finish it unaided.

All 7 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.
