Traits

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

Amphibious.The giant can breathe air and water.

Legendary Resistance (3/Day).If the giant fails a saving throw, it can choose to succeed instead.

Scrying (Requires Storm Rune).The giant can use its crystal ball to cast the scrying spell (save 17).

Storm Rune.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.

Actions

Multiattack.The giant makes three Lightning Blade or Lightning Lance attacks.

Lightning Blade.mw 15 to hit, reach 10 ft., one target. ({@damage 3d8 + 9) slashing damage plus 16 (3d10) lightning damage.

Lightning Lance.rs 13 to hit, range 500 ft., one target. ({@damage 5d12 + 7) lightning damage.

Tempest Call (Requires Storm Rune).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 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.

Storm Giant Tempest Caller

While most storm giants care little for the intricate details of ranking in the ordning, tempest callers proudly claim a position at the pinnacle of that ranking—and few dare to challenge them. Wielding the power of rune magic in addition to the innate magic that courses through them, these storm giants are highly respected. If any giant can draw Annam's attention to the world, it would likely be a tempest caller.

Tempest callers implant crystal balls inscribed with the storm rune into their foreheads or eye sockets, allowing them to see through magical deception. They can also create a momentary vortex of freezing winds and storm clouds around themselves, engulfing their foes in elemental fury.
