Traits
Amphibious. The giant can breathe air and water.
Innate Spellcasting. 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
Actions
Multiattack. The giant makes two greatsword attacks.
Greatsword. Melee Weapon Attack: +14 to hit, reach 10 ft., one target. Hit: 30 (6d6 + 9) slashing damage.
Rock. Ranged Weapon Attack: +14 to hit, range 60/240 ft., one target. Hit: 35 (4d12 + 9) 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 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.
A storm giant is worth 10,000 XP. Using the 2024 encounter budgets (SRD 5.2), this is how many storm giants fit each difficulty for a party of four characters of the same level. A dash means even one would be over the budget.
Budgets add up every monster’s XP, so you can swap some for other creatures of the same total. Try other party sizes and mixes in the encounter calculator.
Against the 7 other challenge 13 monsters in the SRD 5.1, the storm giant has more hit points than 7 of them, which makes it one of the toughest at its CR. See every CR 13 monster.
