So, I can say I'm satisfied with the Shepherd's Staff, one of the new weapons. It's like the Stun Rod but less bulky, easier to use and actually misses way less, making it perfect for newbie gals, especially those with low Strength to avoid accidentally killing your target.
The Great Club seems to be the Concussive version of the Great Sword and the Great Axe, but I never used these weapons much, so I dunno their value.
