Most inquisitors fight insane aberrations and demonic creatures as well as the chaos of heresy. They use the dictum and the mantles of law in order to aid their struggle.
Mantle against Chaos (Sp): You can use protection from chaos on yourself or another creature as a spell-like ability. You can use this ability for a number of minutes per day equal to your inquisitor level (minimum 1). This duration does not need to be consecutive, but it must be used in 1 minute increments.
