Bungling
From Wyvern Source
Description
If you're wearing a lot of armor that causes bungling, or under the effects of some spells, your chance of botching the spell increases. The more armor you have on that can cause bungling, the higher your chance of bungling the spell. Some special kinds of armor allow you to cast spells without penalty. You can find out which ones by experimentation, or in some cases by identifying the item and reading its description.
Bungling the spell still charges you the spell points for the spell.
