Ice Climb. The ant can climb icy surfaces, including upside down on ceilings, without needing to make an ability check .

Torpor. Over the course of one hour the ant enters hibernation. While in this state it doesn’t require food or drink and remains asleep until awoken by its queen, or its resting place is disturbed. When leaving torpor because it was disturbed, a rime ant is sluggish and suffers disadvantage on any Dexterity or attack rolls on the first round of combat.


Claws. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 12 (2d8 + 3) slashing damage. If the target is a Medium or smaller creature, it is grappled (escape DC 13). Until this grapple ends, the target is restrained , and the rime ant can’t use its claws on anyone else. 

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature grappled by the rime ant. Hit: 16 (3d8 + 3) slashing damage. If this damage kills the target, the rime ant severs its head.

Icy Breath (recharge 6). As an action the ant releases a cloud of incredibly cold air in a 30 foot cone. Each creature in the area makes a DC 13 Constitution saving throw , taking 7 (2d6) cold damage on a failure or half damage on a success. In addition, on a failure the creature is coated in a layer of restrictive ice that halves its movement speed until it spends an action to clear it.
