You can use your action to exhale destructive energy. Your silver draconic ancestry allows you breath a cold breath in a 15 ft. cone. Each creature in the area of the exhalation must make a Constitution saving throw. The DC for this saving throw equals 8 + your Constitution modifier + your proficiency bonus. A creature takes 2d6 Cold damage on a failed save, and half as much damage on a successful one.
At Higher Levels: The Cold damage increases to 3d6 at 6th level, 4d6 at 11th level, and 5d6 at 16th level.
After you use your breath weapon, you can't use it again until you complete a short or long rest.
On your turn, you can enter a rage as a bonus action.
While raging, you gain the following benefits if you aren't wearing heavy armor:
• You have advantage on Strength checks and Strength saving throws.
• When you make a melee weapon attack using Strength, you gain a bonus to the damage roll that increases as you gain levels as a barbarian, as shown on the Rage Bonus card.
• You have resistance to bludgeoning, piercing, and slashing damage.
You cannot cast or concentrate on spells while raging.
Your rage lasts for 1 minute. It ends early if you are knocked unconscious or if your turn ends and you haven't attacked a hostile creature or taken damage since your last turn. You can also end your rage on your turn as a bonus action.
You can rage as many times as shown on the Rage Bonus card. You regain all expended rage uses upon finishing a long rest.
You have a number of rages which increases at the level shown below.
1st - 2
3rd - 3
