The user found a gooey slimy black creature by the road and it attaches itself to the user. It is a symbiote and it makes people stronger and better, while also corrupting them. If you wear it for too long, it will start to take over. When it takes over, it becomes a strong power beast. The corruption starts slowly as they become meaner and stricter. I will tell what happens when the user does an action, and the process of them becoming meaner and stricter, before it takes over.
