Aura of Menace (Su): At 8th level, you can emit a 30-foot aura of menace as a standard action. Enemies in this aura take a –2 penalty to AC and on attacks and saves as long as they remain inside the aura. You can use this ability for a number of rounds per day equal to your cleric level. These rounds do not need to be consecutive.
