Oath of the Storm

While you aren't a stalwart defender of nature as a paladin of the antient, you respect the world and hold dear the forces of nature. Gods such as Zues, Thor, or Kord often hold your sway. Brutal and swift, thunderbolts and overwhelming cold help you rule over the world as you see fit. 

Channel Divinity

When you take this oath at 3rd level, you gain the following two Channel Divinity options.

Cloudbank-As a bonus action on your turn you cause the area within 10 feet of you to become heavily obscured for up to 1 minute

Stunning Thunder-As an action on your turn you emit an incredibly loud thunderclap, pick a number of creatures equal to your charisma modifier in a 30 foot cone directed outward from you. These creatures must make a constitution save against your paladin spell dc or become stunned until the end of your next turn.
