I branch off from time to time. I just usually draw about what I know.
13 shield skill is a fun build but not something that needs to be removed. To use a shield with 13 skill, you can only use the lowest tier peasant weapons and you get no other skills. I tried it out. It's fun to trick people into thinking you're an easy kill, but man it's near impossible to kill anyone else with no powerstrike and a cheap club.
