Alastor´s lunatic missile barrage

You summon a barrage of tiny wild magic sparks that fly randomly and explode creating multicolour flames. All creatures in a 60ft-radius centred on yourself including you roll a d6, the targets with the two lowest dice take 6d6 one force damage wild magic sparks. As a side effect from the chaos, all creatures on the area must also take a CD 10 Int saving throw or be confused until the end of their next turn, you have advantage on this throw.
