Right now, there is simply no way to beat the Exorcis. If you talk to her a lot in the various places she appears, you can fight her at Abrasax, but you'll be fighting a different form of her then
ive talked to her multiple times in the two only places she appears at and never had her appear at the Abrasax once she says shes going to the mall but she never appears there so either you didnt add the mall or its glitched out
