Oh, right.  Forgot about that.  Let me double check something though...<br/><br/>*5 mins later*<br/><br/>Okay.  DD doesn't require knowledge of the location, just a specific direction to go.  However, I can't make that attack as per the description of the spell.  Also, I can bring one willing subject with me.  Worst that happens is I take 1d6 damage per five feet shunted, which happens if I end up in a solid wall at the end.
