As soon as Alter had gotten their hands on the Golden Globe, they had been testing its uses and how to fully utilize the item itself. The only people that knew were those from the Bonum Society who were in direct opposition to Alter.
Still, due to the vast amount of item collecting they had over the years, they had figured out various methods on how to test certain items, so it would only be a particular amount of time until they were successful.
During the short amount of time they had the item, they had managed to have somewhat of a success.
