MY group was playing a session tonight and our pysker managed to summon a demon prince from the perils of the warp chart. The black templar(rank 2) in our group activated his solo mode ability Righteous Zeal and charged the demon prince. In the next two rounds he managed to deal 95 wounds with a power axe. As a GM i am wondering the balance of the Righteous Zeal ability that lets him deal this kind of damage and easily dispatch something that is supposed to be a potental TPK encounter. What say you all?
