Energy Dissipator Sphere

You warp the energy balance of space in a 30 ft. radius sphere centered on a point within range. For the duration, when the area of another spell or magical effect of your choice, such as fireball, extends into the sphere, it deals half as much damage to targets within the energy dissipator sphere. This spell only interacts with effects that deal damage by targeting an area of effect, rather than targeting a creature directly.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, its casting does not require concentration.
