On a Dwarven TWF I know the axe comes as a free feat but for end game max dps wouldn't the khopesh be a better source? I know GS D.A. is 2d8 5% crit x3 and the khopesh is 1d10 10% crit and also x3. I am leaning towards the khopesh but would like some opinions from you all. Also is it better to remain pure for the capstone or should I splash either monk, ranger or fighter? I am fairly new to the game and this is my first Barb. I just want it to be viable in the higher content. Thanks in advance for your insight.
