The Wizard is the first promotion of the sorcerer in Might and Magic VII: For Blood and Honor. To be promoted to wizards, sorcerers must seek out Thomas Grey in the Bracada Desert and complete his quest to gather six golem parts and construct a golem.
If playing as a good party, wizards can be promoted to archmages by talking to Thomas Grey in the School of Sorcery in the Bracada Desert and completing his quest to retrieve the book of Divine Intervention from the Breeding Zone in The Pit. Archmages can learn grandmaster light magic.
If playing as an evil party, they can instead be promoted to liches by talking to Halfgild Wynac in the Darkenmore Residence in The Pit and completing his quest to fetch four empty soul jars from the Walls of Mist in Celeste. Liches can learn grandmaster dark magic.
