Sacred 2:Willpower

Willpower Increases resistance against magic spells and additional damage effects (burn, poison, freeze, weaken). Each point of Willpower adds one point to a character's base Spell Resistance Other ways to increase spell resistance include the use of: Using weapons or items which have native Item Modifiers on them such as Spell Resistance X% . Forging Spell Resistance X% into a character's item slots An increase in Survival Bonus which will increase base Spell Resistance How it works Spell Resistance is both a stat & a skill. The stat is based on the characters Willpower stat (so if you have a willpower of 200, you will have a base Spell Resistance of 200 before any other mods are factored in), and it can be increased by a number of means (the +% Spell Resistance mod on items, either native on the item, or forged into items). Spell Resistance is used in a calculation with Spell Intensity (the defender's Spell Resistance v the attacker's Spell Intensity), if the defender "wins" or "succeeds" on this calculation, the attacker's spell's damage is reduced by a % (possibly 30%), if the attacker "wins", their spell damage is not reduced at this point (though it will still be reduced by any resistance or elemental mitigation). Notes Community Patch makes this attribute increase the damage dealt by Lightsabers.
