i got one point........

I thought they were talking about human Bella.
I don't think that their magic relies on their wand. When they were little they showed signs of magic themselves. And they can apparate.

I do agree that, without their wands, wizards are fairly weak, and a vampire (even a Twilight one), would be able to pick them off. It takes an exceptionally skilled wizard to be able to use magic purposefully without a wand. Even Dumbledore and Voldemort still needed to use their wands most of the time!

I don't agree that Bella would be immune to magic. Maybe Crucio au Imperius Curse, because those seem to focus zaidi on the mental, not the physical. Bella's power blocks mental things, not physical ones.

I think Bella would only be immune to mental magic. I'm under the impression that some spells take place in the brain and some spells are physical. Bella would be shielded from the brain spells.

I think Bella would just dodge any spell Bellatrix shot at her. Some may argue that Bellatrix could use that quickly-appear-somewhere spell to catch up to Bella, but that would require that Bellatrix have a hyperactive thalamus and know where Bella is running to. Eventually, Bellatrix would run out of energy and get slow, since she's not a vampire. Vimpires only need to eat every few days to reenergize while she would need to eat every few hours au she'll pass out. Especially since she's so emaciated.
I actually don't understand why Bellatrix wasn't much slower and passing out at times.

I don't think Bella would want to kill anybody.

It never alisema Bella was immune to magic. It alisema Bella was immune to special vampire skills.
And Bellatrix doesn't need her wand -- she a wonderful witch. All she needs to do is think a spell and Bella would drop.

This is going to be another endless debate.
Just take away bellatrix magic, and bela... Vampyness *whatchemucallit* make them both human and see who will won. Imma Just watch the Cats fight and enjoy the onyesha ;)

to make it zaidi interesting tell them the winner will get a kis from edward/voldemort. Battle to death... Start!

Yes, I agree that Bellatrix would be fairly weaker without her wand but she does know how to perform wandless, she isn't as good but it'll be good enough. With a spell as simple as impedimenta followed kwa avada kedavre can easily finish Bella off. Besides, Bellatrix can wandlessly accio back her wand. It'd be simple
And even if Bella happens to get the upper hand and Bellatrix is in danger, she can easily press the dark mark because Voldemort, I believe, would come to her rescue. Though he has no feelings, Bellatrix would be too valuable to be Lost seeing as she's his most faithful deatheater and such a good dueler

Okay let's end it like this. If Bella were still a human and had no help from the Cullens off the Mbwa mwitu loups then Bellatrix would kill her in a heartbeat.

If Bella was a vampire, however, she could kill Bellatrix before she could even take out her wand. I mean, let's be honest guys, Bella is a vampire. Sparkly au not she is still capable of murdering anyone fairly easily. She if she can outrun mountain lions then she could definitely dodge spells and not to mention the fact that Bella is already dead. She'd e immune to avada kedavra (which is the most powerful).

lol no Bellatrix is an all around better fighter and character.

She can fight with zaidi then just her wand she was able to kill Dobby with a kisu as he teleported away. All Bella does is whine and cry for Edward. It was also reveled that Bellatrix can kill using her mind in HBP when she killed the fox. It also doesn't take effort to pick up a wand after it had been dropped. And no she isn't helpless and wont go "oh voldemort........please please please please please save me" She is a strong independent character unlike Bella and had never actually depended on Voldemort. She kinda just giggled when he showed up. Bellatrix without her magic is a dagger wielding bada**! Bella with out her vampire abilities is a weak little girl.
About your side note, I thought that only made her immune to her thoughts being read not magic.Even so Bellatrix could stab her to death and seeing as she's a vampire Bellatrix can pour gasoline au something on her and set it a flame.Bellatrix can never lose. Ever!

One small issue to that.
Bellatrix Lestrange is a soldier of the world's darkest wizard of all time. Not only that she is his sekunde in command for much of the first war. She also carries a dagger in films and vitabu that she is used to using. Even without magic Bella swan simply has no chance.
