The tempest beast can hold its breath for one hour.
A creature that touches the tempest beast or hits it with a melee attack while within 5 feet of it takes 7 (2d6) lightning damage. This damage is increased by 4 (1d6) if the creature is at least partially submerged in water.
The tempest beast makes two attacks: one with its bite and one with its claws.
Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 10 (1d10+4) piercing damage.
Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 11 (2d6+4) slashing damage.
Two creatures within 10 feet of each other and five feet of the tempest beast must succeed in a DC 14 Dexterity saving throw. On a failed save, the target takes 9 (2d4+4) slashing damage and 4 (1d6) thunder damage and is pushed 10 feet away from the tempest beast. If successful, the target takes half the damage and is not pushed back.
