Defeating Vlad Plamus
When you first walk in his room, you will notice that he duplicates himself. You must hit the real Vlad. Use Danny Phantom for this. Jump and shoot any Vlad with your Ghost Shot. He will reflect your shot if you do not jump. Keep hitting all of them until you hit the real one. You will know he is the real one when he falls to the floor. Repeat this three times to defeat him.
