You’ve been exposed to the primordial magic of the Elemental Plane of Fire, granting you the following benefits:

Elemental Magic. You learn the Dancing Lights cantrip, using Intelligence, Wisdom, or Charisma as the spellcasting ability (choose when you select this feat).

Fervent Blaze. You learn the Produce Flame cantrip, using the same spellcasting ability chosen for this feat’s Elemental Magic benefit. You can cast produce flame as normal, and you can also cast it as a bonus action a number of times equal to your proficiency bonus, regaining all expended uses when you finish a long rest.
