Arkhi Brewing Set

Taken all the way down to base materials, one Arkhi Brewing Set is 2 crafting steps deep and needs 1 intermediate — Arkhi Brewing Vat Materials ×4 — which resolves to 1 distinct raw material totalling 4 units, plus 18 crystals.

That bill outweighs 3,935 of the 13,602 recipes tracked here and 437 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 12 are burned by the intermediates, so the real crystal cost is 12 Wind Crystal and 6 Ice Crystal.

Every step is Carpenter work, from a Lv 68 intermediate up to the Lv 68 finish, so one class covers the whole chain.

The single raw material does not appear in the gathering data, so the whole bill comes from vendors, drops or content this site does not track.

Of the intermediates, Arkhi Brewing Vat Materials has the widest use: 8 recipes call for it, spanning eight of the eight crafting classes.
