MOM VOICE [General]

You can make people knock that crap off with just a few words.

   Prerequisite: Mom

   Benefit: Roll a Bluff or Intimidate skill check. All beings with an Intelligence of 3 or higher must roll Will saves with a target equal to your skill check +6. Those who fail the saving throw must immediately stop whatever they're doing for a number of rounds equal to your Charisma bonus, during which time you may attempt to reason with them using Diplomacy or Bluff.

    Those who save against the Mom Voice suffer a -2 penalty to attack rolls and skill checks for a number of rounds equal to your Charisma bonus. If they attack a target who didn't save, the target may attack back with the same -2 penalty.

    All initiatives must be re-rolled at the beginning of the round following the use of Mom Voice.

    Special: Targets of the Mom Voice must be able to hear the user, but they do not need to understand the words spoken; the tone is universal.
