Called Feat 5
Source Pathfinder Advanced Player's Guide
You have heard the Call, and in constantly resisting that persistent demand, you've developed a mental bulwark against effects that would target your mind.
You gain a +1 circumstance bonus to Will saving throws against mental effects. If you roll a success on your saving throw against a mental effect that would make you Controlled, you get a critical success instead.
