From D&D Wiki
Gargantuan giant, chaotic good
Saving Throws Str +17, Con +15, Wis +12, Cha +12
Amphibious. The giant can breathe air and water.
Innate Spellcasting. The giant's innate spellcasting ability is Charisma (spell save DC 20). It can innately cast the following spells, requiring no material components:
Multiattack. The giant makes two greatsword attacks.
Greatsword. Melee Weapon Attack: +17 to hit, reach 15 ft., one target. Hit: 38 (8d6 + 10) slashing damage.
Rock. Ranged Weapon Attack: +17 to hit, range 80/320 ft., one target. Hit: 49 (6d12 + 10) bludgeoning damage.
Lightning Strike (Recharge 5-6). The giant hurls a magical lightning bolt at a point it can see within 500 feet of it. Each creature within 20 feet of that point must make a DC 17 Dexterity saving throw, taking 63 (14d8) lightning damage on a failed save, or half as much damage on a successful one.
Summon Elemental (1/Day). The giant summons an air elemental or a water elemental. The summoned elemental appears in an unoccupied space within 60 feet of its summoner and acts as an ally of the summoner. It remains for 10 minutes, until it dies, or until its summoner dismisses it as an action.
The mightiest and strongest of titans, storm titans dwell in the deepest undersea rifts and the peaks of the highest mountains, rarely staying long in the lands between. A storm titan is always followed by storm clouds, and their eyes seem to crackle with lightning, especially when they are angered or surprised. In battle, they can summon furious magical storms and hurl tremendous bolts of lightning.
