Breath Weapon

You can use your action to exhale destructive energy.
Your Draconic ancestry determines the size, shape, and damage type of the exhalation.

When you use your breath weapon, each creature in the area of the exhalation must make a saving throw,
the type of which is determined by your Draconic ancestry.
The DC for this saving throw equals 12 (8+Con+Prof),
A creature takes 3d6 damage on a failed save, and half as much damage on a successful one.
 The damage increases to 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.

Draconic Resistance

You have Resistance to fire damage.

Path of the Berserker For some barbarians, rage is a means to an end—that end being violence. The Path of the Berserker is a path of untrammeled fury, slick with blood. As you enter the berserker’s rage, you thrill in the chaos of battle, heedless of your own health or well-being.

Frenzy Starting when you choose this path at 3rd level, you can go into a frenzy when you rage. If you do so, for the duration of your rage you can make a single melee weapon attack as a bonus action on each of your turns after this one. When your rage ends, you suffer one level of exhaustion.

Mindless Rage Beginning at 6th level, you can’t be charmed or frightened while raging. If you are charmed or frightened when you enter your rage, the effect is suspended for the duration of the rage.
