The super ability has two drawbacks. First, it takes a very long time to unlock and becomes available only at the very end, but you need to fight here and now. And second, without a mentor, it's very easy to mess up the upgrade process when you're offered something that isn't quite what you need. In my opinion, it's easier to quickly complete this campaign on Chaos difficulty with automated battles and not bother with the long path to the super ability.
