As an action, a creature that you can touch or see within 10 meters must make a Will saving throw.
On a failure, you temporarily disrupt a creature’s ability to mask their true thoughts and intent. The creature is unable to speak a deliberate lie for the duration.
An affected creature is aware of the spell and can avoid answering questions they would normally have responded with a lie. Such a creature can remain evasive in its answers as they remain within the limits of truth.
You can target one additional creature for each additional mana expended. The creatures must be within 5 meters of each other when you target them.
Zone of Truth. You can expend 1 additional mana to create a magical zone that guards against deception in a sphere twice as big as normal centered on a point of your choice within 10 meters. The duration changes to 5 minutes/mana and until the spell ends, a creature that enters the spell’s area for the first time on a turn or starts its turn there must make a Will saving throw.
