Thanks for the replies. I just picked up Arcane Bolt to help speed up my offensive ability (thanks August Drake). I had thought that you couldn't spec out of any trees that you went into but I just read that you can spec out of anything but Main/Secondary powers. Right now my only offense is PA, Spectral Wounds & (as of today) Arcane Bolt. I was also using Black Wand, Nemesis Staff & Sands of Mu. I'm going to pick up some Plasmatic Tasers and give it a shot (thanks Riverdusk).
Cheers!
