You can demoralize multiple enemies.
Prerequisite: Intimidate 8 ranks.
Benefit: When you use Intimidate to demoralize an opponent, you can affect all enemies within 10 feet that can see you, rather than only a single enemy you threaten. Each enemy rolls a separate modified level check to oppose your Intimidate check, but the skill check otherwise works as normal.
