Unlike all the other abilities I have tested I cannot cast the shield skill to prevent my psyker from exploding due to peril overload. I have tested this many times, it has happened to me at least 4 times of which 3 in a row.
Why would it prevent you from exploding? Scriers gaze is set to stop at 100% so it has the weird interaction of preventing an explosion if you cast it and Psykinectic Wrath is supposed to vent peril but the shield has never had that interaction.
