Trueno, the Cataclysm (Japanese: 災厄のトゥルエノ, Saiyaku no Turueno) is a Tyrant in Xenoblade Chronicles X. It is a member of the Filiavent family. It can be found at level 60 at the center of White Phosphor Lake in Cauldros. Unlike most other Filiavents, Trueno will not attack if the party approaches on foot. It sits upon a teleporter, which cannot be used until Trueno is defeated. It is immune to all Debuffs.
