I'm trying to make NPC from a mod - namely http://oblivion.nexusmods.com/mods/9291/? and http://oblivion.nexusmods.com/mods/20161/? - stronger and tougher.

What should I change to make them have large healthpool (I have some 300 myself)?

They should be able to do more damage to my character.

What flags should I use? Auto calc stats? Pc level offset? I already made them 30 level offset but that's not enough. I made them have 100 base health, 100 strenght and endurance and made them Marauder Warrior class (should have max possible health then).
