Blessings of the Hearth

At 1st level, you granted proficiency with heavy armor and martial weapons.

Blazing Wrath

Also at 1st level, you can moltenly 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 fire damage 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.

Channel Divinity: Supernova

Starting at 2nd level, you can use your Channel Divinity to wield the power of the fire and lava with unchecked ferocity.

When you roll fire damage, you can use your Channel Divinity to deal maximum damage, instead of rolling.

Smothering Flames

Beginning at 6th level, when you deal fire damage to a creature, it catches on fire. The creature takes 1d6 points of fire damage at the end of each turn, unless it or another creature within 5 feet of it uses an action to put out the flames. If the flames are not extinguished, they continue to burn the creature at the end of each turn.

Divine Strike

At 8th level, you gain the ability to infuse your weapon strikes with divine energy. Once on each of your turns when you hit a creature with a weapon attack, you can cause the attack to deal an extra 1d8 radiant damage to the target. When you reach 14th level, the extra damage increases to 2d8.

Lavaborn

At 17th level, you gain immunity to all forms of fire damage. You also gain resistance to bludgeoning damage.
