BB, The Big Bad Worg

Keen Hearing and Smell. The worg has advantage on Wisdom (Perception) checks that rely on hearing or smell.

Multiattack: BB attacks with one Bite and uses Huff and Puff if it is available.

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) piercing damage. If the target is a creature, it must succeed on a DC 13 Strength saving throw or be knocked prone.

Huff and Puff (Recharge 6) : BB exhales a strong wind from his mouth, affecting a 15 foot cone in front of him. Creatures in the area of effect must make a DC12 Strength saving throw or be pushed 30 feet backwards. If the creature collides with an object from this forced movement, they take 1d6 bludgeoning damage for every 10 feet of movement they made. If they travel the full distance, they fall prone Objects in the area of effect will instead take 15 points of damage, doubled to 30 if the object in question is considered fragile.

Baleful Baying. BB bays magically. Every enemy within 300 feet of him that can hear it must succeed on a DC 13 Wisdom saving throw or be frightened of the hound until the end of the hound’s next turn or until the hound is incapacitated. A frightened target that starts its turn within 30 feet of the hound must use all its movement on that turn to get as far from the hound as possible, must finish the move before taking an action, and must take the most direct route, even if hazards lie that way. A target that successfully saves is immune to the baying of BB for the next 24 hours.
