Dragon Slayer

Using draconic magic  your rage makes you the ultimate bane of dragons. You gain more resistance and more power to finish them off quickly.

Dragon scales.

Starting at 3rd level you manifest a feature of a type of dragon you choose. You grow scales according to the dragon type you choose when raging.

When you rage you may choose a damage type associated with a dragon.

You become resistant to that damage type when you rage and you deal an extra 1d4 of that type when you hit with a melee attack. This damage increases to 2d4 at 10th

Dragon's Breath.

Starting at 3rd level whenever you take the attack action while raging you may replace one of those attacks with a breath weapon. Choose either a 30 foot line 5 feet wide or a 15 foot cone. Any creature in the area must make a Dexterity saving throw taking 2d8 plus your rage damage or half damage on a success. The DC is  8 + proficiency  + Constitution Modifier

The type of damage is determined by your Dragon Scales choice. The damage increases by 1d8 at certain levels 3d8 at 6th 4d8 at 10th 5d8 at 14th.

Frightening Rage.

Starting at 6th level when you rage choose any number of creatures within 60 feet of you. Those creatures must succeed on a wisdom saving throw or be frightened of you for one minute; they may repeat the saving throw at the end of each of its turns; if they succeed they are immune to this effect for 24 hours.

This ends when your rage ends.
