Red Dragonborn

Breath Weapon: When you take the Attack action on your turn, you can replace one of your attacks with an exhalation of magical energy in a 30-foot line that is 5 feet wide. 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 Fire 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.

Darkvision: You have superior vision in dark and dim Conditions. You can see in dim light within 60 feet of you as if it were bright light, and in Darkness as if it were dim light. You can’t discern color in Darkness, only Shades of Gray.

Fire Resistance: You have resistance to fire damage, and are immune to the effects of hot weather.

Legacy of Red Dragons: You have proficiency in one of the following skills, intimidation or Athletics.

Powerful Build: You count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.
