Gift of the Marid

You’ve manifested some of the power of a Marid, granting you the following benefits:

• Increase your Strength, Constitution, or Charisma by 1, to a maximum of 20.
• You gain a swimming speed equal to your walking speed.
• You gain the ability to breathe air and water.
• As an action, you can shoot water in a 60-foot line that is 5 feet wide. Each creature in that line must make a Dexterity saving throw (DC 8 + your proficiency bonus + your Intelligence, Wisdom, or Charisma modifier [your choice]). On a failed save, a target takes 6d6 bludgeoning damage and, if it is Huge or smaller, is pushed up to 20 feet away from you and knocked prone. On a success, a target takes half the bludgeoning damage, but is neither pushed nor knocked prone. You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
