Electrum Ring

Taken all the way down to base materials, one Electrum Ring is 2 crafting steps deep and needs 2 intermediates — Basilisk Whetstone ×1 and Electrum Ingot ×1 — which resolve to 2 distinct raw materials totalling 5 units, plus 20 crystals.

That bill outweighs 4,201 of the 13,602 recipes tracked here and 564 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 10 are burned by the intermediates, so the real crystal cost is 15 Wind Shard and 5 Fire Shard.

Every step is Goldsmith work, from a Lv 40 intermediate up to the Lv 44 finish, so one class covers the whole chain.

Both raw materials are gathered, and no spot for either 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.
