If there's one thing a fantasy game needs more than anything else, it's spells - magic is one of the major defining elements of the genre. While the HERO System provides gamers with the unfettered flexibility to create any type of spell or magical power they desire, sometimes they don't have the time or desire to do all the work themselves. The Fantasy Hero Grimoire satisfies their needs by providing hundreds of pre-built spells for wizards and other spellcasting characters.
