The giant can breathe air and water.
The giant's innate spellcasting ability is Charisma (spell save DC 17). It can innately cast the following spells, requiring no material components: • At will: detect magic, feather fall, levitate, light • 3/Day each: control weather, water breathing
The giant makes two greatsword attacks.
Melee Weapon Attack: +14 to hit, reach 10 ft., one target. Hit: 30 (6d6 + 9) slashing damage.
Ranged Weapon Attack: +14 to hit, range 60/240 ft., one target. Hit: 35 (4d12 + 9) bludgeoning damage.
The giant hurls a magical lightning bolt at a point it can see within 500 feet of it. Each creature within 10 feet of that point must make a DC 17 Dexterity saving throw, taking 54 (12d8) lightning damage on a failed save, or half as much damage on a successful one.
Some adult storm giants can channel thunderous power through their bodies and release it with a deafening stomp. This ability is represented by the following action option. Thunderous Stomp (Recharge 6). The storm giant stomps the ground, triggering a thunderclap. All other creatures within 15 feet of the giant must succeed on a DC 17 Constitution saving throw or take 33 (6d10) thunder damage and be deafened until the start of the giant's next turn. On a successful save, a creature takes half as much damage and isn't deafened. The thunderclap can be heard out to a range of 1,200 feet.
