Components: S, M

For the duration, you have advantage on all Charisma checks directed at one creature of your choice that isn't hostile toward you. When the spell ends, the creature realizes that you used magic to influence its mood and becomes hostile toward you. A creature prone to violence might attack you. Another creature might seek retribution in other ways (at the GM's discretion), depending on the nature of your interaction with it.
At higher levels: At 5th Level. The creature realizes that you used magic to influence its mood but may not turn hostile toward you based on its disposition. A creature prone to violence might still attack you or seek retribution in other ways.
At 11th Level. You can substitute the somatic and material components of this cantrip with a verbal component that you can weave into a sentence by including the word "friend".
At 17th Level. This spell does not require concentration when you cast it. The creature realizes you have used magic on it 1 minute after the spell ends.
