Seeing that the Cloak of Ruin added more fighting capabilities to him, Adrian rode his rush and immediately used the key given to him by the Seven Devil Gods. This was the agreement they made that he will be given one item from the joint vaults of the Seven Devil Gods should all the Primordial Beasts of Sin be killed. Even if he feels that the Primordial Beast of Pride is still alive, Adrian accepted the key like an advance payment to ease his uneasiness of being granted the key.
The key in question looked incredibly ominous in a way that it screams that it came from Hell. The key is red in color and also emitted a heat that makes the skin crawl. It also has the aesthetic of devil wings on the bow with the key bits having a pointed tip just like the tail of a devil.
