Overpenetration and Cover

Some attacks are powerful enough
to pass right through cover, a shield,
or a victim, and damage someone on
the other side. It’s usually too much
trouble to worry about this, but if it
becomes important (e.g., shooting
through a door, or a bystander behind
your target), see Overpenetration
(p. 408).
