really the only way i know of to beat the baron is if you just drain his focus, i had to respec and check all of my abbilities effects and find some that drain focus even if its just a little focus it helps cause his attacks use focus as well after he gets low focus, he will use a move that deals 2000 points or so to himself in order 2 regain focus, i hope this helps and u may neeed 2 respec to get evough points to learn the moves to drain focus
