Grail Quest Solo Fantasy/YMMV

• Game Breaker: The Luckstone in Book One, which lets you add or subtract 3 from every dice roll from then on. You can even keep it with you for the next two books. Once you have it, the books become a bit easy.
• Seasonal Rot: Realm of Chaos and Tomb of Nightmares clearly suffered from serious proofreading problems, offering several pathways and items that don't do anything, ignoring previously established rules and contradicting themselves repeatedly. Legion of the Dead also has similar faults, but not as prevalent.
