I have been looking at the custom server changes, as well as feat information found on the NWN wikis, and is it true that you can get Greater Two-Weapon Fighting with just base 15 points in Dexterity?
I am asking because I cannot shake away my understanding of the 3.5th edition PnP DnD, where you would actually require 15, 17, and 19 points of Dexterity in order to qualify for the three pre-epic Two-Weapon Fighting feats.
If you mean Improved Two Weapon Fighting, it only requires 15 dex. Greater two weapon fighting is not a feat in nwn to my knowledge.
