Hydaelyn

As an action, you create a powerful geyser of water that erupts from beneath you in a 10ft. radius circle. Each creature in the area must make a Dexterity saving throw, taking 4d8 bludgeoning damage on a failure, and half as much on a success. Additionally, you and any items you are wearing or carrying become invisible for 1 minute, ending when you attack, cast a spell, or after 3 rounds.
