Red Coral Ring

Taken all the way down to base materials, one Red Coral Ring is 2 crafting steps deep and needs 1 intermediate — Basilisk Whetstone ×1 — which resolves to 2 distinct raw materials totalling 2 units, plus 15 crystals.

That bill outweighs 3,130 of the 13,602 recipes tracked here and 416 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

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

Every step is Goldsmith work, from a Lv 40 intermediate up to the Lv 43 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, Basilisk Whetstone has the widest use: 55 recipes call for it, spanning two of the eight crafting classes.
