sour surge
I used shadow volley and got stunned. I then couldn't cast anything or even dash. I was just stuck there. I was able to move around and luckly I had a book auto attack but lost because I couldn't even dash. I took a snapshot after I defeated the boss with a friend. I tried removing the ability all together. But no luck. I just had to sit there and get beat up by a man with a sword.
