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 ×75%, two sources by ×66.6%, and three by ×50%. 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% (×56%), 50% -> 22% (×44%), or 15% -> 6% (×37.5%).
In addition, Vehumet applies two sources of wizardry (×66.6%) to destructive spells. This bonus stacks with wizardry from other sources.[2]
History
- Big Brain was introduced in 0.27.
- Prior to 0.26, staves of wizardry existed, which gave a rank of wizardry.
- Prior to 0.25, potion of brilliance provided a temporary wizardry bonus.
- Prior to 0.14, a staff of wizardry granted a better wizardry bonus than a ring of wizardry.
