Oak Radical

Nothing in this list is craftable in turn, so one Oak Radical is a single step: 3 units of material drawn from 3 base items, plus 7 crystals.

That bill outweighs 3,373 of the 13,602 recipes tracked here and 409 of the 1,552 Carpenter ones, and 9,374 recipes nest deeper.

2 of the 3 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Nothing in the data consumes Oak Radical: it is one of 9 end products among the 9 Carpenter recipes at Lv 35.
