The Amulet of Change is an extremely powerful amulet, capable of changing any aspect of life, except for time. It binds once it finds a master, and is therefore unusable by anyone else, even if the master wishes. The only way the amulet passes on, is if it decides on a new master. It will also choose and stay with the kindhearted, and the strong hearted. Once a master obtains the Amulet, they can change things, through their thoughts and will.
A master can also read the minds of other people, and choose to grant their wishes. The Amulet itself will grow in power every time it has a master, and will reset its power when a master becomes corrupt with that power, a new master is chosen, or if the master so wishes.
