What is theurgy wizard 5e?

In Dungeons and Dragons 5e, theurgy is a subclass option for wizards that focuses on divine magic. The theurgy wizard is able to learn and cast spells from an additional domain of magic, such as the Knowledge or Life domain, in addition to their traditional wizard spells.

This subclass is particularly useful for characters seeking to play a wizard who also has a strong connection to a deity or religious organization within the game world. It offers unique opportunities for role-playing and can provide useful abilities like extra healing spells or divination magic.

The theurgy wizard is introduced in the supplement book, Xanathar's Guide to Everything.
