Dishonest Chamber

Whenever anyone uses a Divination spell to detect an aura within this chamber, the spell instead randomly indicates that some other person or object radiates the aura searched for. If nothing in the chamber radiates the aura detected for, the chamber has no effect.

If the caster of the Divination spell makes a Will save (DC 13), his spell works normally.
