Book of Grudges

At the start of your hero phase, if the bearer is more than 3" from all enemy units, you can say they will read from the Book of Grudges. If you do so, pick 1 enemy unit that is visible to the bearer and roll a dice. On a 4+, a grudge is found. Add 1 to hit rolls for attacks made by friendly CITIES OF SIGMAR DUARDIN units that target that enemy unit until the next grudge is found.
