The DC for this saving throw equals 8 + your Charisma  modifier + your proficiency bonus. A creature takes 2d6 damage on a failed save, and half as much damage on a successful one. The damage increases to 3d6 at 5th level Fighter, 4d6 at 10th level Fighter, and 5d6 at 15th level Fighter. You can use your Breath Weapon a number of times equal to your Constitution modifier, you regain all uses when you take a long rest.

Frightful Presence

At 10th level, as an Action, or replacing one of your attacks when you make the Attack Action, you can emulate a dragon's frightful presence. A target a creature within 120 feet of you, and aware of you. That creature must succeed on a Wisdom saving throw (DC 8 + your proficiency + your Charisma modifier) or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the Frightful Presence for the next 24 hours.

Creatures of a CR or level equal to, or greater than your fighter levels are immune to this effect.

Drake Blade

In addition the the damage that your attack would normally do, you also deal the damage amount and type of your Breath Weapon to the target.

You may not use this feature twice in the same turn.
