A saving throw vs a spell determines your ability to resist, negate, or nullify the effect of a spell. (Note: Some spells have properties in which they can either be COMPLETELY negated or just reduced effects) The base value of a Saving throw is a 10+ on a D20. Saving throws are increased by Spell Rank. So, if someone is casting a Rank 2 spell, the required Saving Throw must be 12+ (Without modifiers) Saving throws are also increased by Skill Modifiers. Wizards - Intelligence Sorcerers - Charisma For example, the base is 10+ as previously stated. So let's say a Wizard is casting a Rank 2 spell with an Intelligence modifier of 2. The required saving throw must be 14+ (Base 10+) + (Spell Rank 2) + (Int modifier of 2) You might say, "Gee, that's kinda much." But trust me, characters gain more Saving Throw resistances through levels. Things that help against spells: Cleric Spells - Wisdom Wiz/Sor - (Rogues can completely negate with Feat), gear, other feats
