Fenrir Special Attacks
Augmented Critical (Ex): The Fenris wolf’s bite threatens a critical hit on a natural attack roll of 18–20, dealing triple damage on a successful critical hit. Additionally, the victim must succeed on a Fortitude save or lose a hand or foot (Fenris wolf’s choice) A victim who loses a foot falls prone and has its land speed reduced to 5 feet. A severed hand make it impossible for the subject to use objects or cast spells with somatic components. The save DC is Strength-based.
Battle Frenzy (Ex): When the Fenris wolf is reduced to 25% of its total hit points, it gains a +4 inherent bonus to Strength and can make an additional melee attack with its bite each round at a –5 penalty. These benefits cease when the Fenris wolf is healed above 25% of it hit points or reaches zero hit points.
Frightful Howl (Su): As a standard action, the Fenris wolf can emit a howl in a 1-mile-radius spread that affects opponents with fewer Hit Dice or levels than it has. The affected creature must make a successful Will save or become shaken. Success indicates that the target is immune to the Fenris wolf’s frightful howl for one day. The save DC is Charisma-based.
Improved Grab (Ex): To use this ability, the Fenris wolf must hit a Huge or smaller opponent with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can try to swallow the foe the following round.
Savage (Ex): If the Fenris wolf successfully trips an opponent, it latches onto the opponent’s body and tears the flesh. This automatically deals an additional 60d6+110 points of damage. If an opponent goes prone for any reason in an area the Fenris wolf threatens, the Fenris wolf can also savage the victim as a free action (treat as the Fenris wolf’s attack of opportunity for the round), even though it had nothing to do with tripping the foe.
Shockwave (Ex): The Fenris wolf can hurl itself to the ground as a standard action to create a localized Earthquake. All creatures within 100 feet of the Fenris wolf must make DC 76 Reflex saves or fall prone. Structures in the radius take 4d6 points of damage instead. The save DC is Strength-based.
Swallow Whole (Ex): The Fenris wolf can try to swallow a grabbed opponent of Huge or smaller size by making a successful grapple check. Once inside, the opponent takes 24d6+22 points of crushing damage plus 12d6+26 points of acid damage per round from the Fenris wolf’s digestive juices. A swallowed creature can cut its way out by dealing 200 points of damage to the Fenris wolf’s digestive tract (AC 35). Once the creature exits, muscular action closes the hole; another swallowed opponent must cut its own way out. The Fenris wolf’s gullet can hold 2 Huge, 4 Large, 8 Medium, 32 Small, 128 Tiny, or 512 Diminutive or smaller creatures.
Trip (Ex): If the Fenris wolf hits with a bite attack it can attempt to trip its opponent (+38 check modifier) as a free action without making a touch attack or provoking an attack of opportunity. If the attempt fails, the opponent cannot react to trip the Fenris wolf.
Unfetterable (Su): The Fenris wolf is under a continuous freedom of movement effect that cannot be dispelled or suppressed by any means. Only epic-level magic can bind the Fenris Wolf, although a specific item or spell would have to be designed for this purpose (such as magical chain called Gleipner).
Skills: The Fenris wolf has a +10 racial bonus on perception and stealth checks. *It also has a +4 racial bonus on Survival checks when tracking by Scent.
