Actions

Multiattack.

The yeti can use its Chilling Gaze and makes two claw attacks.

Claw.

Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 14 (2d6 + 7) slashing damage plus 7 (2d6) cold damage.

Chilling Gaze.

The yeti targets one creature it can see within 30 feet of it. If the target can see the yeti, the target must succeed on a DC 18 Constitution saving throw against this magic or take 21 (6d6) cold damage and then be paralyzed for 1 minute, unless it is immune to cold damage. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If the target's saving throw is successful, or if the effect ends on it, the target is immune to this yeti's gaze for 1 hour.

Cold Breath (Recharge 6).

The yeti exhales a 30-foot cone of frigid air. Each creature in that area must make a DC 18 Constitution saving throw, taking 45 (10d8) cold damage on a failed save, or half as much damage on a successful one.
