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.
The raw spell failure is multiplied by 6 / (7 + sources) if you have at least one source of wizardry. This is applied after calculating spell failure from skills and other modifiers, though failure is modified by a further modifier. If you worship Vehumet, the raw spell failure of destructive spells is further multiplied by 2 / 3, though the total decrease to raw spell failure is capped at 50%. This means you can have up to 5 sources of wizardry apply at once, or 1 for destructive spells with Vehumet.[1]
Generally, the actual decrease to failure rate will be larger than the raw decrease.[2] For example, wizardry x1 will bring failure rates from 80% -> 45% (×56%), 50% -> 22% (×44%), or 15% -> 6% (×37.5%).
History
- The wizardry cap will be removed in 0.31.
- 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.
