I was thinking, since assassins deem average with missile weapons, that they could wield a missile weapon and hide and bash a enemy with it or somthing like that. And it would be somthing like this
hide
You attempt to hide in the shadows
You slip into the shadows unnoticed
bash dame
You swing your heavy crossbow and bash dame brithril in the back for 75 damage
and you could get high crits just like you can using a sharp or thrusting weapon....i couldnt think of anything besides bash what do you think?
