Paladin of Drogos Spoiler

The mighty Paladin's of Drogos are paragons of the power of the dragon god. They take the already defensive prowess of the drogos clerics and take it to new heights, granting resistance as well as AC. Paladins of Drogos excel at countering enemies that rely on specifics elements, giving your party powerful advantages against them. Here are some of the features you would gain upon becoming a Paladin of Drogos...

Draconic Armament: Whenever you use your channel divinity, you may choose a damage type from: fire, frost, poison, acid, or lightning. You and your chosen ally gain resistance to the chosen damage type, and your weapon attacks deal additional damage of that type equal to 1 + your spellcasting modifier. Only one damage type can be chosen at a time, however, any change in damage type applies retroactively to chosen allies.

Draconic Lay on Hands: You have a pool of healing power that replenishes when you take a long rest. With that pool, you can restore a total number of hit points equal to your character level x 5.
As an action, you can touch a creature and draw power from the pool to restore a number of hit points to that creature, up to the maximum amount remaining in your pool. You may apply your channel divinity to this effect.
Alternatively, you can expend 5 hit points from your pool of healing to grant your target immunity to one of the following damage types until your next turn: Fire, frost, poison, acid, or lightning.

New Maneuver: Mighty Guard… Whenever an enemy makes a weapon attack against you or an ally affected by your channel divinity, you may use a maneuver as a reaction to roll 1d4. The target’s AC is increased by 1 + the roll until your next turn. 
New Maneuver: Power of the dragon… Whenever you make an attack roll, if you haven’t used your bonus action this turn, you may use a maneuver to cast Dragon’s Breath as a bonus action this turn. It deals half of its normal damage if cast this way.
