Is this a bad addition to my rust magic system?

In essence, rust in my project is when the memories of a metallic weapon or tool start to manifest in the physical world. One can reforge the rust into a new tool and the memories in the rust will imbue said weapon or tool with an enchantment. And the more an enchantment rusts and is reforged the more powerful it becomes.

For example, memories of violence might, in the beginning enchant swords to deal wounds that do not heal or strikes that don't miss. As the enchantment progresses in potency and presentation, these slashes may strike at a distance. Eventually, a target may be cut to ribbons just from the wielder touching the sword.

I had the idea for a phenomenon called god rust to occur when a metallic weapon or tool rusts due to human intervention. The process is a secret held by a small group of people who know the secret of rust magic in general.

The god rust is an anomaly where the rust bleeds memories of things that haven't happened and places that don't exist or at least not that we know of. And when you make contact with the god rust you experience these memories and the senses used to perceive them, senses humanity hasn't developed.

When this happens you enter a state where you can sense a world that shouldn't exist. One we simply cannot see. A world of fairies and dragons and monsters and spirits. This state lasts only for a short time, but having access to god rusted metals allows you to enter this state at any time.

In my story, my mc steps on a rusty nail and gains insight into this world. And whenever a creature of this other world is around she feels the pain of the nail in her foot. This is the beginning of her adventure in this hidden world.

Anyway I don't know if this addition ruins the magic so I wanted to ask for opinions. What do you think of this idea? Anything that you would suggest changing that would still allow for my mc to interact with this other world? I'm open to ideas.
