using such power often costs the user her life. The anime shows this happening first when Queen Serenity uses it in the past, again when Sailor Moon defeats Queen Metalia, and again in the Sailor Moon R: The Movie. Other depictions show using the crystal to be taxing, rather than fatal. In the manga, no such claim is made about using the Silver Crystal. In both the manga and anime, the Silver Crystal is described as following the heart of its wielder, to the point of either becoming too powerful in the midst of Usagi's confusion, or as inert as a glass bead with her indecision. In the anime, the Silver Crystal was placed on Sailor Moon's Moon Stick to increase her "Moon Healing Escalation" attack. However, Queen Beryl stated that Sailor Moon could not unlock the full potential of the Silver Crystal because she had not awakened as a "full-fledged princess" yet.
