From publisher blurb:
This latest ebook, the seventh in the series, looks at spells specifically designed to counter and frustrate those casters that rely on particular spells and effects in encounters. Within its pages you will find spells to make morale effects, fear spells, charm spells, and mirror image dangerous to use, spells to protect from commonly used abilities and spells, such as Power Attack, glitterdust, and pyrotechnics, as well as spells to ruin the day of those wizards that like to use fireball with pinpoint accuracy into a melee or make heavy use of scrying sensors. The book includes:
29 spells to spoil the tactics of your enemies.
6 new feats on the same theme.
Spell Themes: Spoilers is a spell sourcebook compatible with the Pathfinder Roleplaying Game and suitable for GMs and players of any level.
