Dare

You yell a one or two sentence action you would like the target to take. This target must make a Charisma saving throw, or be compelled to take the action. On a failed save, the target takes this action, and has advantage on whatever roll(s) is/are required to fulfill that action. If the action cannot be fulfilled, the spell's effect is broken and it cannot be cast again by you, and cannot effect the target creature, for 1 day. 

Upon fulfilling the action, the target creature becomes immune to the effect of this spell for 1 day, and gains advantage on its next roll.
