I was shooting signal beams like a machine gun, but then I calmed down. "This isn't working, I must not try to hit her with my eyes, I must try to sense her." I calmed down, and focused my thoughts. Then, once again, heard what I needed to do.
I fired a signal beam directly at her, and when she teleported, I fired another one to my side, hitting her just as she came out of the teleport.
