EMP blast

You release an electromagnetic pulse with a 20-foot radius at a point you can see within range. Constructs within range must succeed on a Constitution Saving Throw against your spell save DC or fall unconscious for 1 minute. At the end of each of the affected targets' turns, they can repeat the saving throw, ending the effect on itself on a success. This spell affects electronic objects within range, automatically shutting them down.

At Higher Levels: When you cast this spell using a spell slot of 5th level or higher, the radius increases by 10 feet for every slot level above 4th.
