The
Murderjack is an evil fey that hunts people, and has an ability much like Frightful Presence (Ex) from the Monster Manual, but has a different name, and greater effect:
Frightening Presence (Su): When a murderjack charges or attacks, it inspires terror in all creatures within 30 feet that have fewer Hit Dice or levels than it has. Each potentially affected opponent must succeed at a DC 23 Will save or become panicked. Creatures with equal or more Hit Dice become shaken only on a failed save. If a victim (whatever its Hit Dice) is caught in the range of three or more murderjacks and fails to resist at least three of their frightening presence effects, she also suffers 1d4 points of Wisdom damage from the soul-numbing fear. This is a mind-affecting fear effect. The save DC is Charisma-based.
The problem? It does not list a duration for the panicked effect. Should I assume it is 5d6 rounds like the Frightful Presence ability?
