Base Class: Fighter
Breath Weapon Mastery
Whenever you use your breath weapon, you may choose to shape it to either a 5 by 30 ft line or a 15 ft cone.
Your breath weapon’s range becomes a 5 ft sphere centered around you. You are not affected by your breath weapon. You may choose not to target creatures that are within range.
Bahamut's Grace
Starting 3rd level, when a creature you can see attacks you, you can use your reaction to increase your AC by your Charisma modifier (minimum of 1) until the start of your next turn. Alternatively, you may use your reaction to increase a single saving throw by your Charisma modifier (minimum of 1)
Additionally, you gain advantage on Charisma (Deception) and Charisma(Persuasion) checks when dealing with Good dragons.
Protector's Strike
Starting at 3rd level, whenever a creature makes an attack against a target other than you within 30 feet of you, you can use your reaction to move up to your speed and make a melee weapon attack against the attacking creature.
Breath and Blade
Starting at 7th level, whenever you use your breath weapon, you may immediately make a melee weapon attack.
Eternal Breath
Dragon Wings
At 15th level, you gain the ability to sprout a pair of dragon wings from your back, gaining a flying speed equal to your current speed. You can create these wings as a bonus action on your turn. They last until you dismiss them as a bonus action on your turn.
You can’t manifest your wings while wearing armor unless the armor is made to accommodate them, and clothing not made to accommodate your wings might be destroyed when you manifest them.
Sacred Shield
From 18th level onward, whenever you use your Second Wind, you may choose a number of creatures up to your Charisma modifier. They gain temporary hit points equal to the hit points you regained. They also gain resistance to the same damage type you gain from your draconic ancestry. Both the temporary hit points and the resistance last 1 minute.
Good catch. I made them up separately but yeah, they should be together. I was doubting on making it a "radius" or a "sphere" area, and I ended up doing half of both XD I'll fix it in the next version :)
Neat. Couple critiques:
- Whirlwind breath should really just be another point in shape breath.
- It's also too small. A 5 foot sphere indicates it's diameter, and 5 feet only fills the user's space. Assuming you wanted to target all adjacent enemies, say a 15 foot sphere centered on you.
- Also, you don't need to specify that it doesn't hurt you too, as the rules indicate that sources of origin are not effected unless otherwise indicated.
