Anyone figured out how to do it, or if it's doable?

Hold your right mouse button on the target, then you get a dropdown menu. I was confused as well, since it doesn't show up immediately, rather after a couple of seconds.

By the way, bashing a chest in always results in at least one broken item.

Also, you can hold shift when you right-click and the menu will come up.

I thought you meant, bashing warlocks... but anyway, these two answered your question :p .

By the way, bashing a chest in always results in at least one broken item.The same thing happens when you explode a fireball near a container. Has anyone yet figured out if the broken item used to be some form of treasure, of if it was simply the container?
