You have learned things that would make any lesser mind falter. As an action, choose a creature within 60 feet. You whisper terrible magical secrets into the creature’s ear. The target must make a Wisdom saving throw. On a failed save the creature takes 4d8 psychic damage and is charmed for up to 1 hour. On a successful save the target takes half damage and is not charmed. If the target fails the saving throw, then their alignment changes to evil for the duration of the effect. At the end of each of the target’s turns before the effect ends, the target can make a Wisdom saving throw. On a successful save, the effect ends. Casting the dispel evil and good spell on the creature restores its original alignment and ends the effect. Only the target hears the whispers. Magical silence does not effect this. You don’t need to share a language with the creature for this spell to take effect, but the creature must be able to understand at least one language.
