Chilled Bones

Entombed Men of Snow. This skeleton is encased within the center of a snowman, giving advantage on attack rolls and stealth checks if hiding within a snowy environment until the creature attacks. After losing this facade and advantage, the Chilled Bones must remain still for 3(1d4) hours to reform into a snowman again as the snow accumulates around it.

Bones Chilled.  While another creature is within a 10ft radius of a Chilled Bones, their movement speed is reduced by 5ft (this effect can stack up to 3 times). Other Chilled Bones are not affect by this movement speed reduction.

Swipe.  Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4(1d6) bludgeoning damage + 3(1d4) cold damage.

Chilled Touch. Cast Chill Touch at first lvl with modified distance and damage; attack: +3 to hit, Touch, one target. Hit: 5(1d8) necrotic damage + 3(1d4) cold damage.

Snowball. Ranged Weapon Attack: +4 to hit, reach 20ft., one target. Hit: 6(2d4) +2 cold damage.

(1/combat) Shattering Cold

    When this creature dies, if it was fatal damage (current hit points + maximum hit points) it explodes, dealing 4(1d6) bludgeoning damage to all creatures within 5ft. Each creature damaged by this ability must make DC 13 Constitution saving throw or take 6(2d4) cold damage and have their movement speed reduced by 5ft.(does not count towards Bones Chilled stack) for 10min. If the affected creatures remain within the vicinity of a warm enough source of flame or heat, the movement speed reduction and duration of Shattering Cold are both reduced to 1.
