• Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.
• Gain access to two additional cantrips dealing that specific damage type from any one class. Furthermore, you can use your spell casting ability when casting these additional cantrips
• On your turn, when you score a critical hit with a cantrip dealing the chosen damage type, or a creature rolls a 1 on a saving throw to save against a cantrip dealing the chosen damage, you add 3+your proficiency damage of the same type.
