From publisher blurb: This volume focuses on options that can be used when your spell is countered, dispelled, dismissed and you fail to cast or maintain it properly. The options within are divided up into four groups: Countered Dampened - aka temporary dispelling Dispelled Failure Each will give various options and effects for each type of spell interaction, from a small chance to not using up spell components, to making it harder to counter your next spell and more.
