Wizardry

Wizardry refers to items and effects that directly reduce your chance of failure when casting spells. These are provided by:

• Rings of wizardry (+3)
• Staves of wizardry (+4)
• Quaffing a potion of brilliance provides a temporary wizardry bonus (+6)

In addition, certain sources provide a wizardry-like reduction of failure rate (by 1/3) that stacks with wizardry:

• Vehumet provides a bonus to Conjurations and Summoning for sufficiently pious worshipers not under penance
• Potions of brilliance

All of these sources stack but very weakly; the first 3 points of wizardry are about as good as the next 9. In no case can failure rate be reduced by better than half using wizardry. Notice that a potion of brilliance will reach the one-half cap by itself.
