Aberrant Mutation. At the start of combat, roll 1d4 for each wolf to determine its mutation:

1. Bone Spines: Any creature that hits the wolf with a melee attack takes 1d6 piercing damage.
2. Warped Jaws: Bite deals an extra 1d6 acid damage.
3. Twisted Limbs: Wolf’s movement increases to 50 ft. and it can climb vertical surfaces as if under Spider Climb.
4. Unnatural Eyes: Advantage on Perception checks and grants packmates advantage on attack rolls within 10 ft.

• Pack Tactics. The wolf has advantage on attack rolls against a creature if at least one of the wolf’s allies is within 5 feet of the creature and isn’t incapacitated
• Fearful Presence (Recharge 5–6). As a bonus action, the wolf emits a warped howl. Each creature of a different species within 20 ft. that can hear it must succeed on a DC 13 Wisdom saving throw or be frightened until the end of its next turn.

Multiattack. The wolf makes two attacks: one with its bite and one with its claws.

Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 12 (2d6+4) piercing damage plus mutation effect.

Claws. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 10 (2d4+4) slashing damage.
