Moonbeam
When a creature enters the area for the first time on a turn or begins its turn in the area, it is struck by silver flames and makes a Constitution saving throw, taking 2d10 radiant damage on a failed save, or half as much on a success.
Shapechangers have disadvantage on this saving throw. On a failed save, a shapechanger is forced to take its original form while within the spell's light.
On your turn, you may use an action to move the beam 60 feet in any direction.
