Calm Emotions 5e
You attempt to suppress strong emotions in a group of people.
Each Humanoid in a 20-foot-radius Sphere centered on a point you choose within range must make a Charisma saving throw.
A creature can choose to fail this saving throw if it wishes. If a creature fails its saving throw, choose one of the following two Effects.
You can suppress any Effect causing a target to be Charmed or Frightened. When this spell ends, any suppressed Effect resumes, provided that its Duration has not expired in the meantime.
Alternatively, you can make a target indifferent about Creatures of your choice that it is Hostile toward.
This indifference ends if the target is attacked or harmed by a spell or if it witnesses any of its Friends being harmed.
When the spell ends, the creature becomes Hostile again, unless the DM rules otherwise.
