Unbreakable Heart

The target creature gains a +4 morale bonus on saving throws against mind-affecting effects that rely on negative emotions (such as crushing despair, rage, or fear effects) or that would force them to harm an ally (such as confusion). If the target is already under such an effect when receiving this spell, that effect is suppressed for the duration of this spell. It does not affect mind-affecting effects based on positive emotions (such as good hope or the inspire courage bard ability).
