Coldlight Abominable Yeti

Snow Camouflage. The yeti has advantage on Dexterity (Stealth) checks made to hide in snowy terrain.

Blinding Light. The Yeti sheds bright light in a 30-foot radius and dim light for an additional 20 feet. As a bonus action, the walker can target one creature in its bright light that it can see and force it to succeed on a DC 14 Constitution saving throw or be blinded until the start of the walker’s next turn.

Icy Doom. Any creature killed by the walker freezes for 9 days, during which time it can’t be thawed, harmed by fire, animated, or raised from the dead.

Unusual Nature. The walker doesn’t require air, food, drink, or sleep.

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.

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.

Cold Ray. Ranged Spell Attack: +3 to hit, range 60 ft., one target. Hit: 35 (6d10 + 3) 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.
