[Interaction, Skill Trick]
You can demoralize multiple enemies.
Intimidate 8 ranks,
When you use Intimidate to demoralize an opponent (PH 76), 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.
