You can activate this boost after making a
successful attack or combat maneuver check.
One ally within 30 feet gains another saving
throw against a non-instantaneous effect that
allows a saving throw affecting them. This
saving throw has the same DC as the original
save. If your ally succeeds, the effect ends. The
ally does not suffer any additional effects for
failing the save. You cannot grant an ally more
than one additional save against a given effect.
