Elm Macuahuitl

Taken all the way down to base materials, one Elm Macuahuitl is 2 crafting steps deep and needs 1 intermediate — Elm Lumber ×2 — which resolves to 2 distinct raw materials totalling 10 units, plus 7 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 5 of those crystals go into the final step; the other 2 are burned by the intermediates, so the real crystal cost is 5 Wind Shard and 2 Ice Shard.

Every step is Carpenter work, from a Lv 16 intermediate up to the Lv 28 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, Elm Lumber has the widest use: 68 recipes call for it, spanning seven of the eight crafting classes.
