The giant's innate spellcasting ability is Charisma (spell save DC 17). It can innately cast the following spells, requiring no material components:

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.

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.
