Hi.
The new text for overrun states that you can do an attack if the maneuver tool overlaps an ennemy unit, and its answered in this thread that you can do the overrun attack on that sole condition, even if the overrunning unit does a partial move and stops before the attacked unit, in melee or not (as seen in this thread.
What about the impossible moves, or "forced partial moves" ?
1) terrain impeding movement
Lets say i have some Swoops. They want to overrun some unit, but that unit is partially hidden behind a wall corner, that the swoops cannot pass (typical example of CRB page 24). they are gonna stop their movement "bumping" the wall, can they do the overrun attack then? (pic related: lets say the obstacle is height 2)
2) unable to reach target's height
Second case: lets say i have some geonosians that want to overrun an unit. But between them, there is a height 4 wall. Geonosians cannot jump over that wall, but they can place the manoeuver tool over it, overlapping the target, and stopping their movement near the wall. Can they do the overrun attack? very similar question: the moving unit cannot reach the height of the target (pictured: swoops with Speeder 1 and Scouts on a Height 2 building). Since the tool overlaps them, can the overrun attack occur?
3): leaving battlefield
Last one, using the "leaving the battlefield" blue insert that states "Units may not voluntarily end a movement with any of its miniature’s bases partially or fully outside the battlefield. A miniature may leave the battlefield temporarily if it ends its movement with its base fully inside the battlefield, such as when a unit with a notched base moves along the movement tool. If this is not possible, the miniature stops its movement when it contacts the edge of the battlefield, then it loses any remaining actions and may not perform any free actions."
Lets say i have a Dewback in that case: he wants to make a move that makes him leaving the battlefield, but since he cannot end his move on the battlefield (due to some terrain or miniature standing in the way), he "bumps" the edge and thus, looses the ability to make a free attack action granted by Relentless keyword.
Lets say i have Swoops in the same exact case: they "bump" the edge, but as Overrun is not described as an action, but as an attack, they can do the overrun attack?
thanks!
