Poison-Tipped Caltrops

Pick up to 3 friendly Skaven units wholly within 13" of this unit to be the targets.

For the rest of the turn, each time an enemy unit uses a Charge ability and ends the move within 1" of any of the targets, roll a D3. On a 2+, inflict an amount of mortal damage on that enemy unit equal to the roll after the Charge* ability has been resolved.
