I beat Baron Brirxs quite easily. I used the biological class. Set Veradux on phalanx mode and max out the dispel thing. Then, only use dispel on him (make sure you have 3 on your bar). He will kill himself using Deep Burning. About 2500 damage per turn. When he gets to around 10000 hp, he will kill himself with one big hit (25000 damage).
