Multiattack

The giant attacks twice with its glaive.

Glaive

Melee Weapon Attack: +12 to hit, reach 15 ft., one target. Hit: 24 (3d10 + 8) slashing damage. If the target is a Large or smaller creature it makes a DC 20 Strength saving throw. On a failure it is pushed up to 10 feet away from the giant and knocked prone.

Rock

Ranged Weapon Attack: +12 to hit, range 60/240 ft., one target. Hit: 39 (9d6 + 8) bludgeoning damage. If the target is a Large or smaller creature it makes a DC 20 Strength saving throw falling prone on a failure.

Fog Cloud (1st-Level; V, S, Concentration)

The giant creates a 20-foot-radius heavily obscured sphere of fog centered on a point it can see within 120 feet. The fog spreads around corners and can be dispersed by a moderate wind (at least 10 miles per hour). It lasts for 1 hour.

Arc Lightning (1/Day)

Up to three creatures within 60 feet that the giant can see make DC 15 Dexterity saving throws taking 42 (12d6) lightning damage on a failure or half damage on a success.

Blinking Blades (1/Day)

The giant magically teleports multiple times within a few seconds. The giant may make one glaive attack against each creature of its choice within 30 feet up to a maximum of 6 attacks.

Reverse Gravity (1/Day)

Each creature of the giants choice within 30 feet is magically hurled 60 feet in the air. If a creature hits an obstacle it takes 21 (6d6) bludgeoning damage. The creatures then fall taking falling damage as normal.

Silver Tongue (1/Day)

One creature that can hear the giant within 30 feet makes a DC 15 Wisdom saving throw. On a failure it is magically charmed by the giant for 1 hour. This effect ends if the giant or its allies harm the creature.
