Calm Heart

 is a unique companion perk in Fallout: New Vegas.

It is acquired by completing Heartache by the Number, Rose of Sharon Cassidy's companion quest, the peaceful way, by obtaining evidence against Alice McLafferty and Gloria Van Graff in order to have the NCR justice system deal with them.

Effects
Rose of Sharon Cassidy receives +50 HP.

 * This perk is broken. Rather than adding 50 points to her maximum HP, it adds 50 points to her current HP. For example, if Cass' max HP was 300, it would display on the Companion Wheel as 350/300, meaning that as soon as she takes 50 damage, the perk will be useless. NOTE: Corrected in patch 1.2.0.31x
