Channel Divinity: Scorching Fury

Starting at 2nd level, you can use your Channel Divinity to unleash the unmatched ferocity of your flames.

When you roll fire damage, you can use Channel Divinity as a free action to deal maximum damage, instead of rolling.

Unrelenting Inferno

Beginning at 6th level, your flames can burn absolutely everything. 
Fire damage dealt by your clerics ignores resistance to fire and treats immunity to fire as resistance instead.

Potent Pyromancy

At 8th level, you add your wisdom modifier to the damage deal with your cleric spells that deal fire damage. This extra damage can only be added once per turn.

Unyielding Conflagration

Starting at 17th level, your mastery over Fire knows no match. 
Whenever you use you action to cast one of your domain spells or Disciple of Flames cantrips, you can use you bonus action to cast one of the cantrips you learned from your Disciple of Flames, with the casting time changed to a bonus action for that casting instance.
