Your commitment to your planar pact grants you the following benefits.
Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.
You always have the Darkness spell prepared. You can cast it once without a spell slot, and you regain the ability to cast it in that way when you finish a Long Rest. You can also cast the spell using any spell slots you have of the appropriate level. The spell’s spellcasting ability is the ability increased by this feat.
You can take a Bonus Action to increase or decrease the radius of a Darkness spell you cast by 5 feet (minimum 5 feet, maximum 25 feet) or move the area of Darkness to a space within 60 feet of you.
