Tuskhelm

After the bearer makes a charge move, you can pick 1 enemy unit within 1" of the bearer. If you do so, roll a number of dice equal to the unmodified charge roll for that charge move. For each 4+, the target suffers 1 mortal wound. If the bearer already has an ability with an effect that triggers after they make a charge move, you must pick which effect applies (you cannot use both).
