Dominic stood up and walked to the blackboard. "I had that problem with my shield potion once. The shield had turned against me and actually locked me out from using my magic. Only lasted for about 30 minutes of course but I had to find a way to unlock it." He started writing an equation in chalk. "In order to do that, you have to create an unlocking potion that basically undoes the over usage of Foxweed. That way you unlock the memories without destroying them."
