In Ultima Online, the 7th character slot is an upgrade that allows players to create an additional character on their account, increasing the total number of characters they can have from six to seven. This feature is particularly useful for players who want to explore different character builds or professions without having to delete an existing character. Acquiring the 7th character slot often requires purchasing a code or bundle from the game's online store. Initially, this upgrade was sometimes packaged with additional storage space, but they are now typically sold separately​
