2 Command Point
The beast exudes a blast of freezing wind in a 15-foot-radius. Each creature of your choice in that area must make a DC 17 Constitution saving throw. On a fail, a creature suffers 4d10 cold damage, its speed is halved, and all attacks it makes until the end of its next turn gain disadvantage. On a success, a creature suffers only half damage.
Actions Bonus
Aspect of the Winter (Level 15)
1 command point
The beast may transform into an Aspect of Winter. The beast's fur turns white as snow and its eyes become pale blue. The air surrounding the beast covers everything in frost. The transformation lasts for 10 minutes or until the beast chooses to revert to its normal form (no action required). The transformation ends early if the beast drops to 0 hit points. The beast may not use this ability again until it has finished a long rest.

Frostbite (Aspect of Winter Only)
When the beast is hit by an attack, the beast may make an attack of opportunity attack against the attacker.
