Pro Tip for the final Boss: skills are: Supression(for the ice blast that deals high damage), Reform or Heroic (for healing) Break or shattered bolt (for stunning) Subversion (for switching damage to healing when supression is under cooldown) and Quick Strike ( when no focus). Passive skills are regeneration, endurance, solidity. The other vacant skills are for damage. Make sure that you max life is many (more than 500 hp..) and turn all your points into vitality.
