3: You constantly exude a thick pheromone that sets all other creatures off, making them be on edge naturally. You gain a bonus on all intimidate checks equal to one half of your hivemaster level. Also, as a standard action, you can unleash a thick cloud of these pheromones, making all opponents within 10 feet of you become shaken for 3 rounds, unless they succeed on a fortitude saving throw with a DC equal to (10 + ½ your HD + your con modifier). Further uses of this ability just makes the duration of the shaken effect last longer, and doesn't upgrade the fear to higher levels. This is a fear effect.
