Beeswax

Nothing in this list is craftable in turn, so one Beeswax is a single step: 3 units of material drawn from a single base item, plus 1 crystal.

That bill outweighs 3,373 of the 13,602 recipes tracked here and 426 of the 1,591 Alchemist ones, and 9,374 recipes nest deeper.

Its single raw material is gathered, and no spot for it is timed, so nothing in the tree waits on the Eorzean clock.

Beeswax is itself consumed by 26 further recipes, spanning six of the eight crafting classes.
