Saving throw

Generally, when you are subject to an unusual or magical attack, you get a saving throw to avoid or reduce the effect. Like an attack roll, a saving throw is a d20 roll plus a bonus based on your class, level, and an ability score. Your saving throw modifier is:


 * Base save bonus + ability modifier

The DC for a save is determined by the attack itself. A natural 1 (the d20 comes up 1) on a saving throw is always a failure. A natural 20 (the d20 comes up 20) is always a success.

Saving Throw Types
The three different kinds of saving throws are Fortitude, Reflex, and Will:

Fortitude
These saves measure your ability to stand up to physical punishment or attacks against your vitality and health. Apply your Constitution modifier to your Fortitude saving throws.

Reflex
These saves test your ability to dodge area attacks. Apply your Dexterity modifier to your Reflex saving throws.

Will
These saves reflect your resistance to mental influence as well as many magical effects. Apply your Wisdom modifier to your Will saving throws.
