Storm Giant Tempest Caller

+6

The giant can't be surprised, and it has advantage on initiative rolls.

The giant can breathe air and water.

If the giant fails a saving throw, it can choose to succeed instead.

3/DAY

The giant can use its crystal ball to cast the scrying spell (save DC 17).

The giant has a storm rune inscribed on a crystal ball. While the object bearing the rune is embedded in its body, the giant can use its Tempest Call action and its Scrying trait. The object bearing the storm rune has AC 17; 50 hit points; and immunity to necrotic, poison, and psychic damage. The object regains all its hit points at the end of every turn, but it turns to dust if reduced to 0 hit points or when the giant dies. If the rune is destroyed, the giant can inscribe a storm rune on another crystal ball in its possession when it finishes a short or long rest.

The giant makes three Lightning Blade or Lightning Lance attacks.

Melee Weapon Attack: +15 to hit, reach 10 ft., one target. Hit: 22 (3d8 + 9) slashing damage plus 16 (3d10) lightning damage.

Ranged Spell Attack: +13 to hit, range 500 ft., one target. Hit: 39 (5d12 + 7) lightning damage.

The giant casts one of the following spells, requiring no material components and using Charisma as the spellcasting ability (spell save DC 21, +13 to hit with spell attacks):

• At will: detect magic, detect thoughts
• 1/day each: control water, control weather (as an action), dispel magic, plane shift, sending, time stop

The giant creates an elemental vortex that fills a 60-foot-radius sphere centered on itself. Each creature in that area other than the giant must make a DC 21 Dexterity saving throw. On a failed save, a creature takes 43 (8d8 + 7) damage of a type of the giant's choosing: cold, lightning, or thunder. On a successful save, a creature takes half as much damage.
