Ki Guardian (Su)
Source: Pathfinder Unchained, p. 17
As an immediate action before he rolls a saving throw against a targeted effect that also targets other allies or an area effect whose area includes other allies, a monk with this ability can spend any number of ki points and designate a number of adjacent allies equal to the number of ki points spent. The monk rolls one saving throw for each designated ally, using his bonus instead of the ally’s. For each successful saving throw, the corresponding ally treats the effect as if that ally had succeeded at the saving throw, and for each saving throw failed, the corresponding ally treats the effect as if that ally had failed the saving throw. If the monk fails any of the saving throws (including his own original saving throw), the monk treats the effect as if he had failed the saving throw. A monk must be at least 6th level before selecting this ki power.
