Divine Cavalry

Divine Cavalry focuses on mounted combat and using this subclass with out a mount is not recommended.

Firearm Proficiency

Starting when you choose this archetype at 3rd level, you gain proficiency with firearms, allowing you to add your proficiency bonus to attacks made with firearms. 

Gunsmith

Upon choosing this archetype at 3rd level, you gain proficiency with Tinker’s Tools. You may use them to craft ammunition at half the cost, repair damaged firearms, or even draft and create new ones (DM’s discretion). Some extremely experimental and intricate firearms are only available through crafting.

Cavalry Training

Choosing the path of the Almighty at 3rd level, you train to fight on horseback (or any mount approved by DM) and in doing so you have learned to fight as one with your steed. You have lost the ability to use Divine Smite while dismounted from your steed.

 You are no longer able to use Divine Smite or add Improved Divine Smite damage to any attack while dismounted. You now may use Divine Smite or add Improved Divine Smite damage to any weapon attack while you are mounted on your steed.

Channel Divinity

Brutal Charge. While you are mounted you can use your Channel Divinity to empower your horse to charge into the enemy or enemies. When you use this you will be able to charge 40ft or less in a straight line(not apart of your movement speed) and trample your enemies. Your first 10ft of movement must not be interrupted by enemies or environment for you to get up to speed. All enemies getting hit must make a wisdom saving throw to evade the charge. If they fail they must make a constitution saving throw to half the damage. All targets that are not larger than your mount are prone after being hit.

Saddle Expert. While you are mounted you can use your Channel Divinity to focus on your next attack letting you add +5 to your attack roll and you can land a critical with a natural roll of 17-20.

United Charge

By 7th level, you have master the art of using your mount's momentum to hit harder with melee attacks. When you move 20ft or more you can add another damage die to your first attack after moving. (Melee only)

You have formed a bond with your mount and feel like you understand it better, doing so has helped you gain proficiency with Animal Handling.

Treasured Companion

If your mount's hp is 0 you will vow to make the one who dealt the final blow pay. You will have advantage against the enemy that incapacitated/killed your mount. While this is happening the enemy must make a wisdom saving throw every turn until it dies or you are incapacitated/dead, unless it is immune to being frightened.

You may also use your Channel Divinity and Divine Smite on this enemy.

Divine Empowerment

At 20th level, you can empower your mount and yourself with divine energy adding a 1d8 of radiance damage to attacks for 1 minute. While Divine Empowerment is active your mount attacks when you attack if the target is within range. This can only used once per long rest.
