Imagine that you're in a room with some NPCs with higher lvl than your characters, but you want to kill them anyway. The way to do it without any scratch is quite easy. Build a barricade made of boxes/crates/tables/chairs, so there's no way through it and initiate a fight (throw a box on them).
Since NPCs don't know, that most of these objects are destructible, they'll just stand in a fight position and won't do anything. So the last step is killing NPCs with some ranged weapons/spells.
Let's give these poor inhabitants of this cruel world some intelligence and possibilities how to manipulate with enviroment.
