Some models have the ability to fly. When a model with Flight moves voluntarily, it ignores vertical distances and can move over structures and models if it has enough SPD to move completely past them. It also ignores the effects of rough terrain. A model with Flight can move onto a structure and end its movement anywhere large enough for its base stand on. When a model with Flight is moved involuntarily, such as the result of a slam, it does not ignore rough terrain or vertical distances and cannot move over structures and other models.
When a model with Flight is targeted by a melee attack made by a model without Flight, the model with Flight gains 2 Power Dice when making its defense roll against the melee attack.
