Version 0.33: This article is up to date for the latest stable release of Dungeon Crawl Stone Soup.
Wizardry refers to items and effects that directly reduce the chance of failure when casting spells. These are provided by rings and the demonspawn mutation Big Brain.
Useful Info
With at least one source of wizardry, your raw spell failure is multiplied by 6 / (7 + sources). This is applied after calculating spell failure from skills and other modifiers, 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 actual failure rates from 80% -> 45% (×56%), 50% -> 22% (×44%), or 15% -> 6% (×37.5%).
There is no hard limit to the number of wizardry you can have.
Several effects are similar to wizardry. They are not considered wizardry, but multiplicatively stack with wizardry and each other:
- Vehumet multiplies the raw failure rate of destructive spells by x2/3. This boost is equivalent to going from 0 sources of wizardry to 2 sources.
- Scarab Form multiplies the raw failure rate of Fire Magic by x2/3.
- Yak Form multiplies the raw failure rate of Ice Magic by x2/3.
Table
| Wizardry | Raw Fail Multi. | Wizardry | Raw Fail Multi. |
|---|---|---|---|
| Wizardry x1 | 75% | ||
| Wizardry x2 | 66.67% | Vehumet | 66.67% |
| Wizardry x3 | 60% | Vehumet + Wiz x1 | 50% |
| Wizardry x4 | 54.55% | Vehumet + Wiz x2 | 44.4% |
| Wizardry x5 | 50% | Vehumet + Wiz x3 | 40% |

History
- Prior to 0.31, there was a raw failure multiplier cap of 50%. This meant you could only have 5 sources of wizardry apply at once, or Vehumet and 1 source of wizardry.
- 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.
References
- ↑ This is true, at the very least, when your (post-wizardry failure rate) < 50%. The smaller the failure, the smaller the % multiplier (keep in mind that it is a multiplier).
