The Annihilus is a Charm dropped by Uber Diablo on Battle.net realms.
Characters may possess only one such charm in their inventory space.
This item holds the honor of being one of only two items to grant a bonus to earned Experience, the other being Ondal's Wisdom.
Despite a sprite for a red colored "Diablo's Soulstone" having existed in the game at the time of creation, this item uses the sprite for Mephisto's Soulstone.
