Wizardry refers to items and effects that directly reduce your chance of failure when casting spells. These are provided by rings and the demonspawn mutation Big Brain.
A single source of wizardry decreases raw spell failure by x75%, two sources by x66.6%, and three by x50%. This is a multiplicative factor, applied after calculating spell failure from skills, though failure is modified by a further modifier.
Generally, the actual decrease to failure rate will be larger than the raw decrease.[1] For example, wizardry x1 will bring failure rates from 80% -> 45% (x56%), 50% -> 22% (x44%), or 15% -> 6% (x37.5%).
In addition, Vehumet applies two sources of wizardry (x66.6%) to destructive spells. This bonus stacks with wizardry from other sources.[2]
