Wizardry 8 is the last installment in the Wizardry series of role-playing video games developed by Sir-Tech Canada. Serving as the third game in the "Dark Savant trilogy," it follows Wizardry VI: Bane of the Cosmic Forge and Wizardry VII: Crusaders of the Dark Savant. Originally published in 2001 by Sir-Tech, it was re-released by Night Dive Studios on GOG.com and Steam in 2013.

In Wizardry 8, the objective is to gather artifacts and place them on a pedestal located in the final zone of the game. This action enables the player to ascend to the Cosmic Circle, where they have the opportunity to attain godhood.

Wizardry 8 offers five potential starting points that build upon the various endings of the preceding games by the same producers.

In a fit of rage, the Dark Savant kills Aletheides. As the player approaches, they discover that the Cosmic Forge has returned to its rightful place in the Circle, the theft of which is detailed in Wizardry VI.

The Dark Savant unveils himself to the player as Phoonzang, the enigmatic deity figure featured in both Wizardry VII and 8, and a former Cosmic Lord. He was cast out by the other cosmic lords for attempting to bestow universal knowledge upon mortals such as humans, T'Rang, and elves. To prolong his life beyond that of an ordinary man, he was compelled to merge with machinery. He then extends an invitation to the party, offering them the opportunity to join him and become cosmic lords alongside him.
