Allright, you're gangrel. Use protean to gain speedbonus (I think you get speedbonus) then just run out the back. Use bloodbuff and fortitude for extra soak, and if you still can't get out. Remember that feeding will heal you (if you can't get out in the first place, try to kill some of the guards to make the running easier, useing bloodbuff, fortitude and protean, and feed to keep your bloodlevel high).
