The Remembering Desert
A strange empty book.
Anyone who has read this book can summon it to their hand as a standard action.
Word of Leon: Conquers Will
Once every year as a bonus action this book can render creatures unconscious. Your current hit point total is how many hit points of creatures this ability can affect. Creatures within 10 feet of you can be targeted for this ability. Subtract each creature’s hit points from the total before moving on to the next creature. A creature’s hit points must be equal to or less than the remaining total for that creature to be affected.
