Before fighting the Witch, you must choose one of the three Exiles; select Code Vision. If you choose the correct one, she will help you defeat the Witch. Once the battle begins, use the Bullet Stop ability to throw the various items in the room at her. They each do a lot of damage. When she casts the Barrier spell, avoid her or your weapon will break and you will be stunned. Make sure to disarm her as soon as possible. Note: Try to make sure the Exile does not get killed. If the Exile is alive at the end of the fight she will show you the exit, but if she dies you cannot see the door with Code Vision. However if you go to the back of the room in the northeastern part (basically where the Witch is standing), you will see a door that you can walk through to get out of the level.
