One advantage of fighting with comrades at your side,
is that if you are somehow knocked unconscious, or just
plain hit hard enough to knock you senseless, one of
your comrades can sometimes assist you, if the time comes
to flee. By being able to keep track of the battle, one
can see when a fallen comrade needs assistance, and can
sometimes give that assistance in order to remove him from
the battle safely. Check 'party rescue' and 'party rescuelist'
commands for further info.
