Played with this build using the 4 player mod over the weekend and it went great. I think I was the strongest character of the group even without armor or a shield. I often felt like I had double or even triple the action points in combat so it was very easy for me to move into combat, take a wack at an enemy or heal an ally, and then run back out of harms way again.
Looks good. So what is your current build?
