Dragons hearth

Your draconic breath grows stronger and more volatile, both in your mortal shape and your dragon form.

This feat replaces the damage, save DC, and recharge/uses of your current breath weapon feature, as described below.

You gain the following benefits:

• Empowered Breath (Dragon Form). While you are in your dragon form, your breath weapon deals 1d10 + your Wisdom modifier damage instead of its normal damage. This damage increases by 1d10 when you reach character levels 6 (2d10), 10 (3d10) cone extends to 20 ft , and 14 (4d10) extends to 25ft
• Dragon Form Recharge. While in dragon form, your breath weapon uses a Recharge mechanic. Once you use your breath weapon, you can’t use it again until it recharges. At the start of each of your turns, roll 1d6. On a 5–6, your breath weapon recharges.
• Empowered Breath (Normal Form). While you are not in dragon form, your breath weapon deals 1d6 + your Wisdom modifier damage instead of its normal damage. This damage increases by 1d6 when you reach character levels 6 (2d6), 10 (3d6) come extends to 20 ft , and 17 (4d6) cone extends to 25ft. 
• Breath Uses (Normal Form). While you are not in dragon form, 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.
• Draconic Spellcraft. Your breath weapon requires a Dexterity saving throw against your spell save DC. A creature takes half damage on a successful save.
