Only issue is the stone can’t fix it again because as the wiki states “ Previously exposed subjects may undergo SCP-113's effects again by re-initiating contact with SCP-113 after approximately 60 seconds have passed. However, in 25% of cases, immediate second exposure to SCP-113 fails to transform the subject correctly. Transformation failure varies in nature, but usually includes massive bone, organ, and tissue damage to the subject, as well as partial or complete obliteration of genitalia. This commonly results in death by organ trauma or internal bleeding.
Failure rate can be affected by subjects not coming into contact with SCP-113 for a lengthy period of time, which varies by subject; patterns are under research. Under normal circumstances, transformation failure rate increases exponentially upon multiple exposures. Subjects who survive rapid, repeated exposure are eventually transformed [DATA EXPUNGED] Further anomalous elements continue to appear as exposure count increases.”
