Walkthrough | Not My Daughter Harry Potter Deathly Hallows 2 Guide
Last update: 11 May 2016
Harry, Ron and Hermione are all fighting their battles, but other Hogwarts students are defending their school as well. Ginny, in order to help her loved one, wants to stop the Death Eaters' march. It won't be easy, as they're very determined to achieve their goal.
The whole action takes place between the debris at the school's courtyard. The enemies will attack in three waves. There will be an automatic save after the first two, but it's still a lots of fighting before you reach that point. I'd suggest retreating from the starting location and going a bit to the back, as otherwise the enemies could flank you. Shoot the appearing mages and check the sides from time to time, as some of them will try to surround you. Use a wide variety of spells, so that you don't have to wait for only one of them to recharge.
In the second wave, you will have to face the dangerous hooded Death Eaters and those attacking with exploding projectiles. With the third group you will probably have to fall back a bit, as enemy units will appear a bit closer to the school than before. Throughout the fights, try to move around the courtyard and find all the collectibles. After you win, the enemies will start bombarding the school, forcing the students to retreat inside.
Inside, Ginny will bump into Bellatrix, who will try to change the young witch into a shooting range. Her mother will try to defend her, ending up in a fight between the two ladies.
The enemy's main advantage is definitely her speed, she won't stay in one place even for a couple second. She will try to teleport all the time, shooting projectiles in the meantime. Even through Molly is much slower, you should be able to dodge most of her attacks by just strafing. If need be, you can also hide behind some covers. Stay in motion and attacks (in accordance with the hint, use Expulso) and Bellatrix should quickly lose her confidence.
Once the Death Eater's health bar is reduced considerably, she will pick up some debris and throw it at Molly. At that moment, keep quickly pressing 2 to eliminate the threat. Afterwards end the fight using the previous tactic.
