Grams' Spellbook

Grams' Spellbook is a tome of spells written by Penny Halliwell.

History
Penny occasionally used spells that were in this book on her granddaughters (only used on Prudence, Piper and Phoebe) when they were young to keep them from misbehaving. The book eventually ended up in the attic when the sisters matured.

In 2004, the book was dug up again when Penny wanted to cast a spell on Wyatt and Chris, her great-grandsons, to end their sibling rivalry. But the spell sent the rivalry to the next set of siblings—namely Piper, Phoebe and Paige. The spell was eventually reversed by Patty Halliwell, who used her own spell to undo it.
