@ Herzog de Puce: The shield stacks with itself every 5s, the value showcased there is miserable because, every minute, the shield's strength is increased by 12 times its original value ( ).

@ Degritone: With that being said, I would recommend you to gave the shield's strength a cap, since its strength could be theoretically infinite.
