Once in combat with the first cultist in Evelyn's hideout (the one that wants to escape towards the orcs when you first enter the place) my first move was to Bullrush him. It either killed, or nearly killed him, however the game crashed with the Bullrush animation being drawn after my character making contact with him.
I do have the infinite Skillbooks&Lockpicks mods applied to the campaign in the latest Steam version of the Game.
