Creature Abilities
Source Alien Core pg. 208
The following creature abilities are listed here because they are shared by many creatures or are highly complex. The statistics for individual creatures might alter the traits, the number of actions, or other rules of these abilities. Anything noted in a specific creature's stat block overrides the general rules for the ability below. In these abilities, “monster” is used for the creature that has the ability, to differentiate it from any other creatures the ability might affect.
Auto-Fire [two-actions]
Source Alien Core pg. 208
The monster attempts to hit each creature in a cone of the indicated size (typically half the range increment of a manufactured weapon) without making an attack roll. Any creature in the area takes the indicated damage, with a basic Reflex save against the indicated DC. This damage is area damage. The Auto-Fire entry can specify additional effects, such as conditions applied on a critical failure. Auto-Fire most often comes from manufactured weapons, in which case the monster must be wielding the weapon, and the Auto-Fire has an expend equal to the number of targets in the area × 2.
