Easiest way to cheat up?

I don't like grinding and spending hours trying to get past something and will mod around the grind, gradually increasing difficulty as I get better through multiple playthroughs.

The first quest in game you are faced with having to kill your foes in ~10 rounds before something bad happens. The math doesn't even add up, counting misses you might average 4-5 damage per round for a total of maybe 50HP before the bad event occurs, and between all the foes piling on there is aggregate of several hundred HP to wipe out. I just want to get on with the story and not redo this scene over and over. I am on balanced difficulty but even the easiest, it still leaves the impossible math.

Is it better to get an "insta-level up" mod and level yourself up a few levels at the beginning or is it better to get something that alters damage (e.g. super damage)? I can't seem to find the latter on Nexus.
