You negate one source of potential danger related to one creature or object that you are aware of within immediate distance for one round. This could be a weapon or device held by someone, a trap triggered by a pressure plate, or a creature’s natural ability (something special, innate, and dangerous, like a dragon’s fiery breath or a giant cobra’s venom). You can also try to foil a foe‘s mundane action (such as an attack with a weapon or claw), so that the action isn‘t made this round. Make your roll against the level of the attack, danger, or creature.
