Best I have is a Magus that can do 32 d6+ 18 at level 10 if he crits (15-20) otherwise he dose 21d6+9 and he has a second attack for 1d6+9. I am able to do that about 22 times a day. And can increase the damage by 50%.
I was trying to build a Nagaji Samurai and becuase of his +2 to handle animals with reptiles and his height and weight I wanted to take the Beast Rider Archetype. But I can't make sense of how that's supposed to work. Could anyone help me out here? Thanks.
