I am currently playing a warpriest (2nd level)and need some help. He is the parties primary front liner and uses a rapier and shield. I am not against level dips but prefer not to. I cannot decide on how to build him from here. I know what I've done so far may not be optimal but what can I do from here, I am not sure if vital strike chain or weapon of the chosen is worth it. Any and all ideas or input is appreciated . Thanks in advance for your help.
