Written by an Elven Mage, this comprehensive book of magic is a priceless text for those that practice the art of magic… unless this copy is a poorly proofread and badly edited reproduction, that is.
The bearer of the Book of Ashur increases their Dispel range by 3" and, unless they roll any natural double, may apply a +1 modifier to any of their Casting or Dispel rolls. However, if the bearer rolls any natural double when making a Casting or Dispel roll, the book has proven to be a poor reproduction, full of glaring errors, and the +1 modifier cannot be applied to that roll.
