Malroth is your constant companion and an invaluable asset. His primary ability is his destructive power; he can instantly break almost any block with a single swing, making resource gathering incredibly fast. In combat, he's a formidable ally, often dealing significant damage and drawing enemy aggro. He also possesses a unique 'ping' ability (activated by pressing 'L' on Switch or 'L1' on PlayStation) that highlights nearby hidden items or quest objectives, making exploration much easier. You cannot directly control Malroth, but he generally follows your lead. Ensure he's equipped with the best available weapons and armor to maximize his effectiveness in battle. His presence is a game-changer for both building and combat.
