I'm usually pretty good with stuff like this, but I can't figure out how to beat Master Alric. He spawns 4 dragons every few seconds and I can do damage on neither the dragons or Alric. I can only do damage by critting the dragons but when I finally get them down he spawns 4 more. If I leave them alone, he just keeps spawning more anyway until I'm overwhelmed Alric himself has some sort of shield that mitigates/reflects damage. My character is a gunner. Any help?  
 
Edit: not sure how this made it onto general discussion, I was sure that I was on the Torchlight boards. Sorry for the confusion.
