Your words, gestures, and touch invest an object no larger than yourself with an aura of doom, fear, and doubt for one day. Creatures that can hear and understand you feel an urge to move at least a short distance away from the object. If a creature does not move away, all tasks, attacks, and defenses it attempts while within the aura are hindered. The duration of the aura is extended by one day per level of Effort applied. The aura is temporarily blocked while the object is covered or contained.
