Tree Slice Tower

Taken all the way down to base materials, one Tree Slice Tower is 2 crafting steps deep and needs 1 intermediate — Walnut Lumber ×3 — which resolves to 1 distinct raw material totalling 11 units, plus 12 crystals.

That bill outweighs 5,999 of the 13,602 recipes tracked here and 581 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 6 are burned by the intermediates, so the real crystal cost is 9 Wind Shard and 3 Ice Shard.

Every step is Carpenter work, from a Lv 25 intermediate up to the Lv 32 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, Walnut Lumber has the widest use: 128 recipes call for it, spanning eight of the eight crafting classes.
