All the Holy Avenger ability in NWN does is give 1d6 Divine damage AFAIK. If you try and build Carsomyr the way it was built in BG2 nobody will ever be able to wield it - it will be Level 27 or something. 
[/QUOTE]Hehe, well apart from all my spelling errors in above post.. (sorry, head is tired, too hot and alot of other excuses) the level requirements is IMHO crap in the light of PnP but probably a good thing versus Munchkin players online.
The thing is I think at least that if you have the true character line edited in the NWN.ini file you can use items regardless of this level check.. Tada!
Well, some item s are incredibly strong, whereas others are very good, but also very very weak. I mean the colak that gives a +1/5 soak damage and protection.. How many monsters at CR7 can hurt you plentifully any way?? And it takes away most of your hard earned money...
