The following two items are new magic items for characters to discover in the adventure ‘Heart of the Iron God.’
Boccob’s Blessed Book
Wondrous item, rare
This well-made tome is always of small size, typically no more than 12 inches tall, 8 inches wide, and 1 inch thick. All such books are durable, waterproof, bound with iron overlaid with silver, and locked. A wizard can fill the 1,000 pages of a blessed book with spells without paying the 50 gp per level cost.
Robe of Powerlessness
Wondrous item, rare
A robe of powerlessness appears to be a magic robe of another sort, such as a robe of stars or robe of the archmagi.
Curse. As soon as a creature dons this garment, it takes a –10 penalty to Strength and Intelligence (to a minimum of 1), forgetting spells and magic knowledge accordingly. The robe can be removed easily, but in order to restore the mind and body, the character must receive a remove curse spell followed by a greater restoration spell or similar magic.
Both of these magic items are featured in the adventure ‘Heart of the Iron God.’
