When a creature is the subject of a dangerous spell or effect, it often receives a saving throw to mitigate the damage or result. Saving throws are passive, meaning that a character does not need to take an action to make a saving throw—they are made automatically. There are three types of saving throws: Fortitude (used to resist poisons, diseases, and other bodily ailments), Reflex (used to avoid effects that target an entire area, such as fireball), and Will (used to resist mental attacks and spells).
