Ebony Lumber ★★★★

Nothing in this list is craftable in turn, so one Ebony Lumber is a single step: 11 units of material drawn from 2 base items, plus 4 crystals.

That bill outweighs 5,999 of the 13,602 recipes tracked here and 581 of the 1,552 Carpenter ones, and 9,374 recipes nest deeper.

1 of the 2 raw materials come out of the ground, and one of them is time-gated: Ebony Log (4:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Ebony Lumber is itself consumed by 34 further recipes, spanning five of the eight crafting classes.
