I have to wonder how, exactly, this fellow ended up with a Subterranoid weapon.  I'm inclined to say 'no' since that's a wee bit like wandering about Rohan with an Orc blade in hand...and letting a friend and ally have one isn't really something the Gnomekin seem likely to do.<br/><br/>May I humbly suggest Kanquan instead of Arimite Knife Fighting?  It seems to fit the backstory a bit better.<br/><br/>That's a whole lot of quirks you have listed.  How many did you actually buy?
