The hound has advantage on Wisdom (Perception) checks that rely on hearing or smell.
The hound has advantage on an attack roll against a creature if at least one of the hound's allies is within 5 feet of the creature and the ally isn't incapacitated.
Melee Weapon Attack: +5 to hit, reach 5ft., one creature. Hit: 7 (1d8 + 3) piercing damage plus 7 (2d6) lightning damage.
The hound exhales a line of lightning that is 20 feet long and 5 feet wide. Each creature in that area must make a DC 12 Dexterity saving throw, taking 21 (6d6) lightning damage on a failed save, or half as much on a successful one.
The storm hound turns into a bolt of lightning and magically teleports up to 40 feet to an unoccupied space it can see. Upon arrival, a thunderous force explodes from the storm hound. Each creature in a 15-foot cube originating from the storm hound must succeed on a DC 12 Constitution saving throw. On a failed save, a creature takes 9 (2d8) thunder damage and is pushed 10 feet away from the storm hound. On a successful save, a target takes half damage and isn't pushed. In addition, unsecured objects that are completely within the area are automatically pushed 10 feet away from the storm hound. Using this action emits a thunderous boom audible out to 300 feet.
