Horse Chestnut Ring of Gathering

Taken all the way down to base materials, one Horse Chestnut Ring of Gathering is 2 crafting steps deep and needs 1 intermediate — Horse Chestnut Lumber ×2 — which resolves to 1 distinct raw material totalling 10 units, plus 31 crystals.

That bill outweighs 5,754 of the 13,602 recipes tracked here and 568 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 24 Wind Crystal and 7 Ice Crystal.

Every step is Carpenter work, from a Lv 81 intermediate up to the Lv 81 finish, so one class covers the whole chain.

Its single raw material is gathered, and no spot for it is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Horse Chestnut Lumber has the widest use: 39 recipes call for it, spanning six of the eight crafting classes.
