Have you tested this and know if this works for sure? It doesn't appear to be doing anything for me... at least the vitality boosts that I can see are not increasing health at all.
I'm aware that already-generated mobs in savegames won't pick up buff modifications like this, but I even made sure I was using brand new areas at level 8 where the mobs were (I believe) definately spawning from scratch when zoning to someplace brand new. Even tried to start a new game.
I also tried removing every mod, just to make sure another script wasn't messing with it. Also tried compiling my own ncs from your script. Nothing for any of them.
I remember the old k_ai_master script (like talchia's) would work, but the k_def_buff one doesn't seem to even do anything.
Any help would be appreciated. Thanks.
