Conversation Between Silversabeast and Parvin

Hey there. I wanted some advice please. I am trying to get the 'Mind Over Matter' achievement but can't figure it out. I know it has to do without attacking the enemy so I am equipped with an 'On block damage titan500' gem, but still can't get it it even though i do not make an attack. any pointers?
