You attempt to enchant a humanoid you can see within range. It must make a Wisdom saving throw, and does so with advantage if you or your companions are fighting it. If it fails the saving throw, the target will be convinced that they are an alien infiltrator in human form, and may act accordingly. The target will not be aware that the belief is false, and any evidence to the contrary will be dismissed or rationalized away.

The spell can be countered by a dispel magic or similar spell. Once the spell ends, the target will realise it was enchanted.
