Breath Weapon

Dragon fire is the classic example, but a breath weapon can be a cloud of poisonous gas, a bolt of lightning, or a stream of acid. Breath weapons are usually supernatural abilities, and a creature needn’t be able to breathe to use one.


When using a breath weapon, a creature is actually expelling something from its mouth rather than conjuring it by means of a spell or some other magical effect. Most creatures that have breath weapons are limited to a number of uses per day or by a minimum length of time that must pass between uses. Even if a creature has more than one type of breath weapon, the time between uses is a time during which it can’t use any of its breath weapons.

Using a breath weapon is typically a standard action. No attack roll is necessary. The breath simply fills its stated area, which is usually defined like a spell’s area. Any creature caught in the area must succeed on the appropriate saving throw or suffer the breath weapon’s full effect.


Breath weapons that deal energy damage allow a Reflex save for half damage (DC 10 + 1/2 breathing creature’s racial HD + its Con modifier; the exact DC is given in the creature’s descriptive text). Some breath weapons allow a Fortitude save or a Will save instead of a Ref ex save. In many cases, a creature that succeeds on its saving throw against such a breath weapon suffers a reduced effect.

Creatures are immune to their own breath weapons.
