A Land Far Away

OK, so I haven't tested everything out yet but there seems to be some inconsistencies in NWN2 about what makes a weapon good aligned, for the purpose of bypassing the DR of numerous creatures.

What I'm curious about is:
1) an exhaustive list of what makes a weapon 'good aligned' in the current nwn2 implementation
2) how this differs from 3.5 rules and
3) is this something we will be changing to closer match 3.5, or sticking with Obsidians implementation

almost every creature in the demon and devil categories requires a weapon to be good aligned and/or be made of a special material so I'm interested in what exactly makes a weapon 'good aligned' since I can't seem to find it in the nwn2 documentation.

What about evil aligned weapons so we can kill celestials.

if i recall correctly in 3.5 there are some weapons that give negative levels when a good or evil character wields it. would be easy to say that those weapons are either good or evil.

examples are unholy and holy damage

Its hardcoded, so there is no way I can look at it or alter it myself (without reworking it and intercepting the damage in every creature's OnDamaged event). OE tells us any weapon with a +something vs. alignment is treated as aligned the oposite. ie, +2 vs. evil is a good weapon. Not sure if there is more, or if OE is planning on altering that at all, you'd have to look on their forums.

Has anyone had a chance to check to see if NWN2 has cursed items, with the requisite inability to remove said item from their inventory (or their hand)?
