Compelled Truth

Created originally as an enchantment for weapons "of Vindication," this spell is used to compel the truth from its victim by force.  The somatic component, and thus the reason for a casting time of one action, for this spell is a successful non-lethal attack.  Then, you must ask a question in a language the target of the spell can understand or the spell fails.  Once the attack succeeds and a question is asked, the target will be under a charmed condition for 1 minute.  During this minute, the target will be compelled to answer the asked question truthfully or else take psychic damage.  The spell will deal damage if the target refuses to answer the question for the entire duration of the spell, or instantly if the target lies.  Multiple castings of the spell can be in effect on the same target simultaneously, and will resolve in the order they were cast.  The spell cannot be cast multiple times simultaneously for the same question.  If the spell deals damage due to a lie, it ends immediately.

If the target is rendered unconscious or unable to respond before the end of the spell, it ends harmlessly unless the target is the one that rendered themselves unconscious or unable to answer.  Being rendered unconscious from the psychic damage of the spell, whether or not it was intentional, does not count as the target rendering themselves unconscious for the purposes of this spell.
