Seeing as though this odd reality warping girl is a threat you decide to take to VIOLENT MEANS of PACIFICATION. You psychically steal away the arm, sword, and other miscellaneous objects circling about her and proceed to pelt her with them in the most nonchalant manner you are capable of. Which is pretty damn nonchalant because you're an emotionless ghost. There isn't much else for you to do save nonchalant stuff.

The bitch sadly isn't falling so easily to your attempts at harming her. Instead she absorbs the arm into some manner of black aura that you're beginning to believe may be part of her as opposed to some manner of black aura. She begins to shriek in some unworldly tongue. It sounds quite similar to the speech of the outergods. In fact it appears to be some manner of broken dialect of Eldritchese.
