Belthazar's Haunting Question

You attempt to interrupt a creature from taking an action deemed to be self-destructive, pointless, wasteful, stupid or otherwise detrimental. The caster must make meaningful eye contact with the target and speak the words "Are you sure?" The target creature is filled with a sense of impending dread and self doubt, causing it reconsider it's action and my choose different, and hopefully less stupid course of action. This spell will fail if the player controlling the creature has an Intelligence or Wisdom score lower than 8. The target my counter the effects of this spell by confidently stating that yes, he is, in fact, sure.
