Eternal Darkness

You create a space of darkness that draws in magic. For the duration, any spell of 3rd level or lower cast by a hostile creature that targets a creature or object within a 30-foot radius of you fails and has no effect. If the spell is 4th level or higher, make an ability check using your spellcasting ability. The DC equals 10 + the spell's level. On a success, the spell fails and has no effect.
At Higher Levels.
When you cast this spell using a spell slot of 5th level or higher, the interrupted spell has no effect if its level is less than or equal to one level below the level of the spell slot you used.
