When determining your character’s ability scores, increase one of those scores by 2 and increase a different score by 1, or increase three different scores by 1. Follow this rule regardless of the method you use to determine the scores, such as rolling or point buy.

The “Quick Build” section for your character’s class offers suggestions on which scores to increase. You’re free to follow those suggestions or to ignore them. Whichever scores you decide to increase, none of the scores can be raised above 20.

Your character can speak, read, and write Common and one other language that you and your DM agree is appropriate for the character. The Player’s Handbook offers a list of languages to choose from. The DM is free to modify that list for a campaign.

Your size is Medium.

Your base walking speed is 30 feet.

When you take the Attack action on your turn, you can replace one of your attacks with an exhalation of magical energy in a 15-foot cone. Each creature in that area must make a Dexterity saving throw (DC = 8 + your Constitution modifier + your proficiency bonus). On a failed save, the creature takes 1d10 cold damage. On a successful save, it takes half as much damage. This damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).

You can use your Breath Weapon a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

You have resistance to cold damage.

You don't need air.

Starting at 5th level, you may empower your breath weapon with the cold glow of the moon. Any creature caught in your breath weapon must also make a Constitution saving throw, the DC of which is equal to 8 + your Constitution modifier + your proficiency bonus. On a failed save, their speed is reduced by half for one minute. Once you use this ability, you can't do so again until you finish a long rest.
