Rot Coven

At the start of the hero phase, you can pick 1 WIZARD from each Rot Coven in your army. Add 1 to casting, unbinding, and dispelling rolls for that WIZARD in that phase. Add 2 instead of 1 if that WIZARD is within 3" of 1 other WIZARD from the same Rot Coven. Add 3 instead of 1 if that WIZARD is within 3" of 2 other WIZARDS from the same Rot Coven.
