Undyed Linen

Taken all the way down to base materials, one Undyed Linen is 2 crafting steps deep and needs 1 intermediate — Linen Yarn ×2 — which resolves to 1 distinct raw material totalling 2 units, plus 4 crystals.

That bill outweighs 3,130 of the 13,602 recipes tracked here and 386 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 2 are burned by the intermediates, so the real crystal cost is 4 Lightning Shard.

Every step is Weaver work, from a Lv 32 intermediate up to the Lv 33 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.

Undyed Linen is itself consumed by 67 further recipes, spanning four of the eight crafting classes.
