Blood Frenzy.

The loup garou has advantage on attack rolls against a creature that doesn't have all its hit points.

Legendary Resistance (2/Day).

When the loup garou fails a saving throw, it can choose to succeed instead.

Regeneration.

The loup garou regains 10 hit points at the start of each of its turns. If the loup garou takes damage from a silver weapon, this trait doesn't function at the start of the loup garou's next turn. The loup garou dies only if it starts its turn with 0 hit points and doesn't regenerate.
