In her description the level 5 Cleric Malgorzata Niska doesn't have "Aura of Madness". This seems to be correct since she would need level 8 to get that Domain Ability. In her Tactics section it's written tho, that she activates her "Aura of Madness".
So my questions are:
If she does have that ability: Why?
If she doesn't: What does she do instead?
If you have the book yourself, she and the encounter is described on pages 12 and 13 (Event 3: The Cult of Gyronna).
Google didn't help me on this one, sorry if that question has been answered already.
