Multiattack

The hound of the night makes two Bite attacks.

Bite

Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 14 (2d8 + 5) piercing damage plus 4 (1d8) cold damage, and the target must succeed on a DC 14 Strength saving throw or be knocked prone.

Frost Breath (Recharge 5-6)

The hound exhales frost in a 15-foot cone. Each creature in the area must make a DC 14 Dexterity saving throw, taking 27 (6d8) cold damage on a failed save, or half as much damage on a successful one.

Teleport (Recharge 4-6)

The hound magically teleports, along with any equipment it is wearing or carrying, up to 60 feet to an unoccupied space it can see. Before or after teleporting, the hound can make one Bite attack.
