Nope, this comment is wrong. Ancient Wisp *is* the Legendary Wisp. I just killed it and got the achievement. I can only think this was either a typo in the achievement list, or that the actual name of the boss changed from "legendary" to "ancient" at some point during development and the list wasn't updated.

Also can confirm that taking fall damage after the Wisp spawns doesn't count as "getting hit" for the purposes of the achievement.
