like a magic book that you can have different color crystals in it and when you hold it in your hand you can pull out a fire ball with your other hand and throw it at stuff and it will light on fire that would be for a red crystal a blue crystal could shoot water or ice water could slow ice could stun if yellow crystal was a thing it could shoot a blot of lightning or it could be a ball of lightning and of green was a thing it could shoot like a vine and when you use the book it would take like 10% charge from the crystal or 5% it would be cool if this was added (if something is worded bad i`m sorry)
