Chardalyn Yeti

Fear of Fire. If the yeti takes fire damage, it has disadvantage on attack rolls and ability checks until the end of its next turn.

Siege Monster. The yeti deals double damage to objects and structures.

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

Multiattack. The yeti can use its Chilling Gaze and makes one headbutt attack.

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

Charming Gaze. The yeti targets one creature it can see within 30 feet of it. If the target can see the yeti's helmet, the target must succeed on a DC 12 Wisdom saving throw against the Chardalyn or take 12 (4d4) psychic damage and then be charmed for 1 minute. 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 15 Constitution saving throw, taking (5d8) cold damage on a failed save, or half as much damage on a successful one.
