Well, there's some nonsense we get later about how the shield only protects her from *non*-physical powers, which is why Jasper can still affect her (his powers affect hormones and the like in her bloodstream. Doesn't explain how she's immune to Kate and Jane, since pain is caused by tripping synapses in the brain, but yeah).

So, long story short, your Holy weapons ought to work just fine. Have at them! ^_^
