Supernatural Abilities (Su)

Supernatural abilities are magical but differ from spells in key ways. Unlike spells, which can be interrupted while being cast, supernatural abilities can’t be disrupted in combat. They aren’t subject to spell resistance or dispel magic, but they don’t function in areas where magic is suppressed or negated.

The text of a supernatural ability indicates what type of action is required to use it, as well as how often it can be used. If a supernatural ability doesn’t specify what type of action is required to activate it, it requires a standard action.

The DC of a supernatural ability is typically equal to 10 + half the level of the creature using it + the creature’s relevant ability score modifier, as detailed in the ability’s description.

Supernatural abilities are often denoted with the abbreviation “Su” in parentheses next to the ability’s name.
