I'm thinking about making a GS +++ for dealing with undead. This character is going to be a dex-based Drow pure rogue assassin using daggers. However, daggers won't help getting through most undead DR, so I'm curious what people would recommend for a weapon type for this item.
Kukri can take advantage of dex to damage/to hit and beats zombie slashing DR, as well as utilizing TWF, but may not be worth taking proficiency feat in case I TR into another class.
Quarterstaff does skeleton blunt DR, also has dex to damage/to hit, and if I TR this can be used with proficiency by all classes.
Light mace has to use strength to damage/to hit, but has proficiency by all (again, in case of TR), can make use of TWF, and beats skeleton DR.
I know this is mostly a preference thing, so I'm just looking for advice. Additionally, if two of these weapons could be made, what do you think would be best? 2 kukris? kukri/light mace? quarterstaff/kukri (both types of DR)? 2 maces?
