Arcane Severance

You attempt to assault the weave around a creature channeling a spell you can see within range. The creature of your choice must succeed an Intelligence, Wisdom, or Charisma saving throw(whichever is your spellcasting ability), on a DC of 10 + your character level. On a success, this spell fails. On a fail, the creature loses concentration on any spell they are concentrating on. Further, the creature cannot cast the same spell for 1 turn after its concentration is disrupted. Any creature attempting to cast a ritual spell that fails this saving throw is disrupted and must restart their ritual.
