First, you add your CR to the weapons, so it's 15.<br/>Second, it was my mistake for not telling you all - the guy has Evade of 5, which applies as a penalty to your attacks. So Aevala scored a Partial success, only dealing half her (STR+DR).<br/>MadPanda, I guess you'd rather roll your own attack? You can describe it, too.<br/><br/>The assassin will act reasonably and is trying to run away, BTW, so I'll roll for him after you all declare your actions ;).
