Frostbite Aura: At the start of its turn, each creature within 10 feet of Arctikorr takes 5 (1d10) Cold Damage and must succeed on a DC 15 Constitution Saving Throw or have their movement speed reduced by 10 feet until the end of their next turn.

Icy Regeneration: Arctikorr regains 10 hit points at the start of its turn if it has at least 1 hit point and isn't in sunlight or fire damage.

MultiAttack: Arctikorr makes three attacks: one with its bite and two with its claws or one attack with its bite and one attack with Icy Shard Barrage.

Claw. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 14 (2d8+5)) slashing damage.

Icy Shard Barrage (Recharge 5-6).  Arctikorr hurls icy shard in a 30 foot cone. Each creature within the area must make a DC 16 Dexterity Saving Throw, taking 22 (4d10) cold damage on a failed save or half as much on a success.

Icebound Leap (Recharge 4-6).  Arctikorr leaps up to 30 feet in a straight line, landing with a thunderous crash. Each creature within 10 feet of its landing spot must make a DC 15 Strength throw or take 14 (3d8) Cold Damage and be knocked prone.
