The Tome of Power accompanies Corvus through his adventures. When activated, it consumes defensive mana and temporarily increases the strength of Corvus' weapons and spells. It is the first defensive spell in the game, as Corvus begins the game with it.
- While used in a different fashion, this spell is pretty much the same as the Tome of Power artifact in Heretic and Hexen II.
