Suddenly the stone changes shape, turning into an 3" by 8" smooth tablet somewhat resembling a smart phone.
Jon notices the change and immediately tries tapping on it like a smartphone, but nothing happens. He tries making a small benign wish no result.
"Did I just kill the stone?" He thinks to himself, he looks it over a few more before giving up. He sighs, partially out of disappointment and partially out of relief, "That thing was way too dangerous anyways, he thinks to himself."
