Ultima VII: The Black Gate + Forge of Virtue

And while Exodus was destroyed, some of his essence remains in the Dark Core, which must be destroyed to rid Britannia of his evil once and for all. To accomplish this, several tests of virtue must be passed, originally designed by Lord British as part of the Quest of the Avatar. The rewards of completing the add-on's quests are plentiful and can make the main game easier: the Avatar's stats will be raised to their maximum and a new, powerful weapon will be made available, able to vanquish even the most dangerous foes with a single strike.
