Well the easy way would probably be decreasing his stats through the console, which could be a bit boring, but you can change all of his stats. You can target him with the console open and type in: setav (name of the attribute, skill or stat) (skill level) Type it without the () of course. The other thing you could do is open up the construction set for oblivion, load the mods Oblivion.esm and OOO + all of its plugins, find the guy that kicked your @ss and manually edit his stats, then save it and load the mod you made in OBMM. that should solve your problem. I'm sorry if it won't, but I'm not really familiar with OOO scripts and how they affect NPC levelling.
