Some magic creatures have the supernatural ability to instantly heal damage
from weapons or to ignore blows altogether as though they were invulnerable.
The numerical part of a creature's damage
reduction is the amount of hit points
the creature ignores from normal attacks. Usually, a certain type of weapon can overcome this reduction. This information is separated from the damage
reduction number by a slash. Damage
reduction may be overcome by special materials, by magic weapons (any weapon with a +1 or higher enhancement bonus, not counting the enhancement from masterwork quality), certain types of weapons (such as slashing or bludgeoning), and weapons imbued with an alignment
. If a dash follows the slash then the damage
reduction is effective against any attack that does not ignore damage
Ammunition fired from a projectile weapon with an enhancement bonus of +1 or higher is treated as a magic weapon for the purpose of overcoming damage
reduction. Similarly, ammunition fired from a projectile weapon with an alignment
gains the alignment
of that projectile weapon (in addition to any alignment
it may already have).
reduction completely negates the damage
from an attack, it also negates most special effects that accompany the attack, such as injury type poison
, a monk
's stunning, and injury type disease
reduction does not negate touch attacks, energy damage
dealt along with an attack, or energy drains. Nor does it affect poisons or diseases delivered by inhalation, ingestion, or contact.
Attacks that deal no damage
because of the target's damage
reduction do not disrupt spells.
Spells, spell-like abilities, and energy attacks (even nonmagical fire) ignore damage
reduction is instant healing
. Sometimes damage
reduction represents the creature's tough hide
or body,. In either case, characters can see that conventional attacks don't work.
If a creature has damage
reduction from more than one source, the two forms of damage
reduction do not stack. Instead, the creature gets the benefit of the best damage
reduction in a given situation.
