I recently picked up my xbow shotgunner again (I used to have one with two light xbows, but they are two slots now):
10/27
3 ps
9 ath
9 wm - 180 xbow and 90 1h
6 shield
Don't expect it to be very strong, but it's amazingly fun. You basically run up to an enemy (easier if he is not aware) and shoot him. The xbow normally needs two hits for light-medium armor, so you can kill pretty consistently with it. Oh and if somebody tries to attack you, just kite untill he stops or take your dagger and buckler and spam the fuck out of him
