Certainly it’s possible to make an extremely effective spellcaster without adding any of the feats in this book. However, rather than attempt to create must-have feats that patch rules in the game, or open entirely new ways to fill crucial party roles, this book is designed to just add some fun options. These are feats that give a spellcaster an interesting or defining quirk. These feats allow characters to pluck out their own eyes for magic sight, have power over spells they create (and name after themselves), and invoke magic items with words of power that frighten their enemies. They are designed to make spellcasters (and the games they appear in) interesting, unexpected, and memorable.
