Baron Abilitys Needed:Aggression, magic bolt/wound/sunder. Use aggression on the Paladin and keep attacking the Baron with magic bolt/wound/sunder and put Veradux on defensive so he can heal.
Paladin Abiliys Needed:Magic bolt/smash or anything that does major damage, break, subversion and maybe electro bolt. Frist get the paladin down to 1000/900 hp then use break and then subversion and then he should heal 1700 and die.It may take more than 1 go. If the Paladin uses intervention after you used subversion use electro bolt and then he should heal and die.
Ignition Abilitys Needed:Heroic Motivation(lvl 2 or 3 and 2 of them in your ability bar), electro bolt and anything that does major damage. (Put team mates on aggressive) Keep attacking Ignition and when he uses fate on any of your team member use Heroic Motivation. Carry on attacking and when he uses Dark Regeneration use electro bolt.
for ignition i used shater bolt(x2), heroic motivation(x2), electro bolt, quick strike and block(x2). and i had amber in tactical and veradux on defensive. when ignition used fate on veradux or amber i used heroic motivation and when he casted it on me i used block.
lol those are simple go get a walkthrough for the bonus area, just like paladin with the healer or medic person gets to 900000 or so make sure you break him into that health them use subversion it took forever for me to get enough points to get to subversion though
I had few problems with the ignition but with assassin a crit coup de grace equal's the paladin's damage, just keep him concussed with break and other stuns, I have an average of 1000 dmg with normal attacks on assassin...
