Tiamat's Champion

The 5 Headed progenitor of Chromatic Dragons has chosen you as her Champion. She has has gifted you a portion of power, one that may come with a hidden cost.

As you grow more power may be obtained, but at what cost?

This feat grants you one of two Options:

Tiamat's Rage Once per Long Rest you can enter Tiamat's Rage, while raging your connection to Tiamat's power grows, granting you Draconic gifts.

While raging, you gain the following benefits if you aren’t wearing heavy armor:

• You have advantage on Strength checks and Strength saving throws.
• You have resistance to bludgeoning, piercing, and slashing damage.

If you are able to cast spells, you can’t cast them or concentrate on them while raging.

Your rage lasts for 1 minute. It ends early if you are knocked unconcious or if your turn ends and you haven’t attacked a hostile creature since your last turn or taken damage since then. You can also end your rage on your turn as a bonus action.

When you enter your rage, you can transform, revealing the bestial power within you. Until the rage ends, you manifest a natural weapon. It counts as a simple melee weapon for you, and you add your Strength modifier to the attack and damage rolls when you attack with it, as normal.

You choose the weapon’s form each time you rage:

Bite. Your mouth transforms into a bestial muzzle or great mandibles (your choice). It deals 1d8 piercing damage on a hit. Once on each of your turns when you damage a creature with this bite, you regain a number of hit points equal to your proficiency bonus, provided you have less than half your hit points when you hit.

Claws. Each of your hands transforms into Draconic claws, which you can use as a weapon. It deals 1d8 slashing damage on a hit. Once on each of your turns when you attack with a claw using the Attack action, you can make one additional claw attack as part of the same action.

Tail. You grow a lashing, spiny tail, which deals 1d10 piercing damage on a hit and has the reach property. If a creature you can see within 10 feet of you hits you with an attack roll, you can use your reaction to swipe your tail and roll a d8, applying a bonus to your AC equal to the number rolled, potentially causing the attack to miss you.

Tiamat's Breath: 

Tiamat has granted you access to her Breath. Your Draconic Breath  is now empowered and you deal increased damage with your breath weapon.

You exhale multicolored flames in a 30-foot cone or a 35ft by 5ft line. Each creature in that area must make a DC 15 Dexterity saving throw. On a failed save, the creature takes 3d10 damage of a type of your choosing: acid, cold, fire, lightning, or poison. On a successful save, the creature takes half as much damage.
