An item, that when interacted with in some fashion, randomly changes the way someone thinks, their personality and their morals.
Can you be a bit more specific than that? We've already got a couple SCP objects on the site that alters individuals' personality.
Overall… it seems pretty bland. Right now, you have an object with a clearly defined activation and function, with no context or backstory, essentially a generic magic object. I recommend adding some more to this, because at this point the idea seems to be more of an anomalous object than an SCP that would merit specific Foundation containment.
What's the background behind this thing? What significance did it have before it was contained? What makes it more than thing #9001 the Foundation locked up? Was it ever special to someone? Was anyone special to it? Why does it exist anyway?
To quote vezaz, "Get away from "type of object" or "sort of creature" and instead start thinking about stories you want to tell. Start looking for moments in your everyday life that give you pause, that are unusual, or that make you go off into a daydream. Then think about bringing the reader to that same moment."
Why should the reader care about this thing?
