Spellfire Spark
You gain the following benefits.
Magic Absorption. Once per turn, when you take damage from a spell or magical effect, you reduce the total damage taken by dice:1d4|noform|noparens|avg (1d4). You can’t use this benefit if you have the Incapacitated condition.
Spellfire Flame. You learn the Sacred Flame cantrip. Intelligence, Wisdom, or Charisma is your spellcasting ability for this spell (choose when you select this feat). You can also cast this cantrip as a Bonus Action a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a Long Rest.
