Veil of Warding

You touch a creature and provide a ward against effects that beguile the mind, shrouding the creature's head with an invisible arcane veil.

For the duration of the spell, the target has advantage on saving throws against effects that alter the mind, such as feeblemind or charm person.

If the target fails the saving throw, they can choose to negate the spell's effect by expending the veil. The spell then ends.
