At Grimmord place, go up the stairs (you will have to know the explosion spell) and blow up the couch. On the top level blow up all the doors and 10 felix feliz's will appear at the bottom level.

When the target is red cast Stupefy. When voldemort appears you cannot Stupefy him. Cast your spells at the Deatheaters.

Select "Options" at the main menu, then select "Unlockables". Press C, A, 2, Minus, Down, B to strengthen your Protego Totalum charm so that nothing can get through it.
