Ability Scores and Saving Throws
In the standard rules, the only ability score
that can affect a saving throw is Wisdom (affects
saving throws vs. spells). The DM does, however,
have the option to apply ability score bonuses
and penalties to other saving throws:
Strength: Modifies saving throws vs. paralysis
and turn to stone.
Intelligence*: Modifies saving throws vs.
mind attacks (charm, confusion, control, fear,
feeblemind, sleep, etc.).
Wisdom*: Modifies saving throws vs. spells.
Dexterity: Modifies saving throws vs. wands
and dragon breath.
Constitution: Modifies saving throws vs. poison (but not vs. death ray).
Charisma: No bonus to saving throws.
* Combined modifier cannot exceed + / — 3.
