The Husker can add half of how much it moved horizantly last turn to its movement this turn, up to a maximum of 4x it's base movement. Any creatures that rolls a natural 1 on any attack or abality check even if they would ignore that dice through advantage or rerolls within 10ft of the husker, falls prone & take 1d6 bludgeoning damage. That natural role number increases by 1 for every overlap of this abality.
