As two actions, you close off areas of a creature’s mind communication and social interaction of a creature that you can touch or see within 20 meters. The creature must make a Will saving throw.
On a failure, it loses knowledge of all languages (including telepathic and body language) and is treated as illiterate for the duration.
It may still “speak”, and to it they sound completely normal, but to anyone else they appear as complete gibberish. Verbal components, if used, are not limited by this spell.
A creature can repeat the saving throw each minute, ending the effect on itself on a success.
You can target one additional creature for each additional mana expended. The creatures must be within 5 meters of each other when you target them.
