Harlequin's Panoply

Description: Models in this unit have a 5+ invulnerable save. Each time this unit makes a Normal Move, Advances, Falls Back or makes a charge move, until that move is finished, models in this unit can move horizontall through models and terrain features (they cannot finish a move on top of another model, or its base). Each time a melee attack is made against this unit, subtract 1 from that attack's hit roll.
