Destroy Credibility

You infuse a piece of a humanoids writing with malicious intent. Those whom read a piece of written text produced by the creature for the next 5 hours must succeed a charisma saving throw against your spell save DC as affected by a charm or see the text as against their own will and in total opposition to their core values or goals, on a success the creature reads it as normal but is aware of its obfuscating presence. This does not affect the targeted creature, but can be detected by them using spells such as Detect Magic.
