An Instantaneous spell is any spell where the game effect is immediate and the spell ends. The most common examples are combat spells (spells that reduce Challenge Points, Body Points, Mind Points, or Spirit Points), and spells that move a target. Instantaneous spell effects are permanent. For instance, the damage a character takes from a firebolt spell does not wear off when the spell ends, and a door unlocked using magic remains unlocked. An Instantaneous spell may not be maintained.
