You thunderously rebuke attackers. When a creature within 5 feet of you that you can see hits you with an attack, you can use your reaction to cause the creature to make a Dexterity saving throw. The creature takes 2d8 lightning or thunder damage (your choice) on a failed saving throw, and half as much damage on a successful one. You can use this feature a number of times equal to your Wisdom modifier (a minimum of once). You regain all expended uses when you finish a long rest.
Present your holy symbol and speak a prayer censuring the undead. Each undead within range that can see or hear you must make a Wisdom saving throw. If the creature fails its saving throw, it is turned for 1 minute or until it takes any damage. A turned creature must spend its turns trying to move as far away from you as it can, and it can't willingly move to a space within 30 feet of you. It can't take reactions and for its action it can only use the Dash action or try to escape from an effect that prevents it from moving. It can use the Dodge action if there is nowhere to move.
You wield the power of the storm with unchecked ferocity. When you roll lightning or thunder damage, you can use your Channel Divinity to deal maximum damage, instead of rolling.
You can summon the primal spirit bound to your soul. As an action, you can expend one use of your Wild Shape feature to summon your wildfire spirit, rather than assuming a beast form. The spirit appears in an unoccupied space of your choice you can see within 30 feet of you. Each creature within 10 feet of the spirit (other than you) when it appears must succeed on a Dexterity saving throw against your spell save DC or take 2d10 fire damage. The wildfire spirit is friendly to you and your companions and obeys your commands. See this creature’s game statistics in the wildfire spirit stat block. You determine the spirit’s appearance. Some spirits take the form of a humanoid figure made of gnarled branches covered in flame, while others look like beasts wreathed in fire.In combat, the wildfire spirit shares your initiative count, but it takes its turn immediately after yours. The only action it takes on its turn is the Dodge action, unless you take a bonus action on your turn to command it to take one of the actions in its stat block or to take the Dash, Disengage, Help, or Hide action.The wildfire spirit manifests for 1 hour, until it is reduced to 0 hit points, or until you use your Wild Shape again.
