[@Strawberry425] Answering all your questions.

Yes the armour is penetrable by any high powered projectile. Any anti armour rounds, super strength thrown objects or punches, magic powered physical attacks yada yada basically anything above an assault rifle bullet can and will penetrate her armour.

And it doesn't completely block hits either. It absorbs [b]a part[/b] of damage sustained, not all of it. Meaning to say she will still hurt when she gets shot, but her armour absorbs some of the pain for use as energy. 

Her daemons act independently of her, yes, but they respond to her commands more than they do their own thing. If she asks, they do the thing.

Yes it is only focused on a single target. Forgot to add that in, whoops. 

Any sufficiently powered attacks will hurt. Doesn't have to be magic. Basically anything above a standard attack will hurt her past her disease body. 

That rule applies to whoever she chooses. Allies, enemies, it can be anyone if she chooses so. 

A lot of this is up to my own discretion, so I'll put a limiter on whatever you see as too overpowered.
