Starlight Domain

Your calling to Bahamut's light has changed you.
In life you were a reflection of that light - a beacon to the world.
Now, in death, you are a raging storm of stars given mortal form once more, an instrument of Justice to banish the Evil that taints this world.

Weapons of Justice

At 1st level, you become a champion of justice, gaining the tools to distribute that justice to the wicked.
Gain Proficiency with Martial weapons and Heavy armor. In addition, whenever you would deal Weapon Damage, you may replace that weapons damage with Radiant or Fire damage.

Rebuke of Starlight

At 1st level, you may retaliate with your inner starlight power to any who assail you.
When a creature within 5 feet of hits you with an attack, you may use your Reaction to force the creature to make a Dexterity saving throw against your Cleric Save DC.
The creature takes 2d8 Radiant or Fire damage (your choice) upon failing the saving throw, and half as much damage on a successful one. This damage increases as you increase in levels, evolving to 2d10 at Lv.10, 2d12 at Lv.15, and 2d20 at Lv.20.

You may use this feature a number of times equal to your Wisdom modifier. You regain all expended uses when you finish a Short Rest.

Channel Divinity: Wrath of the Stars

Beginning at 2nd level, you learn to harness the powers of Bahamut to inflict the complete wrath of the Stars upon your foes.
When you roll Radiant or Fire damage, you may use a charge of your Channel Divinity to deal maximum damage in place of rolling.

Starlight Pulse

Upon reaching 6th level, your connection to the Starlight that guides you allows you to move those before you.
When dealing Radiant or Fire damage, you may Push a creature of Large size or smaller 10ft.
In place of Pushing the target, you may instead add 1d10 Radiant or Fire damage to any Cantrip or Weapon attack that already deals Radiant or Fire damage.

You also gain the Extra Attack feature - allowing you to make 2 weapon attacks when you take the Attack Action

Starlight Strike

Upon attaining 8th level, your attacks now shine with radiant fire.
Your attacks become infused with divine Starlight energy. When you hit a creature with a weapon attack, you may cause the attack to deal 1d8 Radiant or Fire damage.
When you reach 14th level, the extra damage increases to 2d8.

Starlight Flight

Upon reaching 17th level, your body is filled with the divinity of the stars, allowing you to fly.
You gain a Flying speed equal to your walking speed.
