Actions

Multiattack.

The kraken makes three tentacle attacks. One of them can be replaced with a bite attack, and any of them can be replaced with Fling.

Bite.

Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 16 (2d8 + 7) piercing damage.

Tentacle.

Melee Weapon Attack: +11 to hit, reach 20 ft., one target. Hit: 14 (2d6 + 7) bludgeoning damage, and the target is grappled (escape DC 16). Until this grapple ends, the target is restrained. The kraken has ten tentacles, each of which can grapple one target.

Fling.

One Medium or smaller object held or creature grappled by the kraken's tentacles is thrown up to 60 feet in a random direction and knocked prone. If a thrown target strikes a solid surface, the target takes 3 (1d6) bludgeoning damage for every 10 feet it was thrown. If the target is thrown at another creature, that creature must succeed on a DC 16 Dexterity saving throw or take the same damage and be knocked prone.

Lightning Storm.

The kraken creates three bolts of lightning, each of which can strike a target the kraken can see within 150 feet of it. A target must make a DC 16 Dexterity saving throw, taking 16 (3d10) lightning damage on a failed save, or half as much damage on a successful one.
