- Markshire PCs:
generally the same named type of bonus does not stack. The exception to this are dodge bonuses to AC and anything labeled “universal” bonus. So if the damage bonus from GMW and the damage bonus from the mithril are the same name then they won’t stack. What will happen is the larger bonus will override the smaller one. On a side note, one bug on NWN is that bonuses to attributes all stack. In DnD the bonus from your +2 dex bracers don’t stack with your cat’s grace bonus, that was intentional but somehow they missed that in NWN.
