Magnis Arduns are enemies in Xenoblade Chronicles. They are members of the Ardun family, and can be found on Bionis' Leg. They often appear in pairs and are usually both level 77. They are the only source of Ardun Elder Beards, which are needed for the reconstruction of Colony 6 and for Replica Monado 1. As soon as they see the party and attack they will almost always use "Armu Plough", an extremely strong physical attack, and will most likely kill the party if they have just reached Bionis' Leg in the story.
