My players have come up with a plan, to deal with enemies in a barn. They have managed to successfully sneak close enough, undetected to the barn, where the "bad guys" are holding up, and have caught them unaware.
Their plan is simple, lob a few molotovs in to the barn, and bar the door so they can't escape. Their exact plan of action is-1 is aimed at the group of NPCs and the 2nd at the hay loft above,
So, any suggestions as to how I should resolve this would be very helpful.
