Warhammer Fantasy

the caster chooses a creature they can see within range, and sings a song that appeals to their deepest desires. An illusion manifests of the subject of their drive, their most personal desire. The creature must succeed a wisdom saving throw with disadvantage, or be easily manipulated by the song and the illusion. Such a powerful charm can make the target turn on their friends and families, and even knowingly throw their life away. Even damage won't dissuade and won't be enough to break the enthrallment. But the subject of the desire must remain ever out of reach, which gives opportunities for the target to succeed a saving throw and break out of the spell. The spell lasts for 10 minutes, but is possible to be recast. However, once free from enthrallment, if the subject was not aware of it, and no one tells them, they might be able to fall for the same illusion a second time at a later date.
