Relentless Arduran is a quest-exclusive Unique Monster and Boss in Xenoblade Chronicles 2. It is a member of the Ardun family and can be found at level 99 at Kloom Farm in Gormott Province after supplying Pekka with a certain amount of food for his Ardun. It will respawn after checking the named tombstone.
Despite all of the Ardun forms leading up to Relentless Arduran, it has the appearance of a Balgas. This may imply that Balgas are the same species as Armus and Arduns and probably a dominant male (Ardun) in Xenoblade Chronicles 2.
If the Ardun is killed before he grows into Relentless Arduran, then he will not spawn on that profile. In order to try again, either the player must begin a new New Game Plus or create a new save entirely.
