You begin to merge your current plane of existence with one of the many material planes in a 30-foot-radius, 60-foot-tall cylinder centered on a point that you can see within range.
Whenever a spell that deals damage begins at, ends inside, passes through, or overlaps with the cylinder, you can use your reaction to attempt to neutralize the spell by making an ability check using your spellcasting ability. The DC for this check is equal to 10 + the level of the spell slot used to cast the spell (DC 10 for cantrips). If you succeed, the spell ends immediately and has no further effect.
As an action on your turn, you can attempt to banish an otherworldly creature in the area. A creature of your choice within the cylinder must succeed on a Charisma saving throw, or else be teleported to its native plane. Humanoids and creatures native to your current plane of existence automatically succeed on this saving throw.
