Cone of Power

You project a blasting force of energy from your body, disrupting nearby magical forces.

You project a 30 foot cone from your body. Any creatures that start their turn in the cone and are concentrating on a spell must make a Constitution saving throw or lose concentration on their spell. Creatures that attempt to cast a spell while within the affected area must make a Constitution saving throw. On a failure, the spell fails and has no effect. 

The cone moves with you and continues projecting from your body for the duration of the spell. You can change the direction of the cone as a bonus action, otherwise its orientation remains the same, regardless of your movements or the direction you are facing.
