There are two stories to the Cursed Cup of Immortality, the one that was fabricated and sold to adventurers upon return, and the real story.

Also known as the Circle of Soul Stealing, a devious and powerful trap
"John. This is your final power. Precognition. Don't you see? The ability to know what is going to happen. And, if you know what is going to happen, then you can stop it."

A second transformation is possible, but the creature will have to go through the whole process again.
