WAY OF THE WRATHFUL FLAME

Ember Selica At 3rd level, when you take this subclass, you can forgo adding your ability modifier to the damage dealt by your unarmed strikes. If you do so, you instead deal additional fire damage equal to your Wisdom modifier. In addition, when you deal fire damage to a creature that is resistant or immune to fire damage, you may force them to make a Strength saving throw, being shoved away from the source of damage on a failure. The distance they are pushed is equal to your unarmored movement bonus.

Ingenium Tantrum At 6th level, your anger at getting damaged allows you to fully unleash. While below half your maximum hit points, you may use a bonus action to spend 2 ki points. For the next minute, you have advantage on all attack roles, and creatures have advantage on attack roles against you. Fire damage dealt by your unarmed strikes is doubled. This affect ends early if you are knocked unconscious or you spend an action to calm yourself. In addition, while this affect is active, when you are hit by a creature within 5 feet, you may use your reaction to deal fire damage to that creature equal to your martial arts die, rolled twice.

Final Spark At 11th level, you have learned how to let the fires within you rage. As an action, you may spend 3 ki points to cast Fireball at 3rd level, centered on yourself. You may use this feature twice, and you regain any expended uses on a short rest. In addition, fire damage dealt by your unarmed strikes ignores resistance to fire damage.
